Y'all need to get your self into board games. And I don't mean Monopoly.
1) They move on
When playing games (good games, not monopoly) you become invested - sometimes more heavily than anyone would think is reasonable - you can spend the better part of your evening cultivating delicate alliances or constructing economic engines hinged on fluctuating resources, building constantly towards your goals; only to have progress and victory thwarted by anything from a statistically improbable streak of bad luck, to out right betrayal or simply being bested, fair and square by an honest opponent.
But then you move on, you pack up, put the rivalries and losses, the alliances and victories behind you and move on to the next game; a fresh new slate where everything is new and everything is different. Games can help you get better at doing this, they can acclimatize you to moving on and letting go. They can even reward you for doing so as players that learn to abandon poor strategies and let go of grudges will generally perform better in most games.
2) They keep control
Playing a game with any amount of strategy (not monopoly), is nearly all about control. As you play more games over a spectrum of genres and a multitude of mechanics, a good player will look for the moves that leaves them in the most control. The more you play, the better you'll get at seeing opportunities for control. You'll find for example, that moving up the score track early in a game will come at the expense of control later in a game.
Think of board games as a kind of microcosm. Play enough of them often enough and you'll begin to get competent at 'staying in control' whilst fighting a pandemic or building a competitive power grid. But then it should begin to bleed out into your general decision making. Perhaps only in a small way at first but if you spend enough of your recreational time practicing at 'staying in control' in a host of different game situations, eventually it'll effect your decision making at work, in how you manage your finances or even in how you prioritize your free time.
3) They embrace change
Nothings going to teach you to embrace change like a board game. If you don't you're just going to lose. A good board game will keep the landscape changing around you forcing you and your opponents into a kind of race to evolve; adapt or die.
Some people fight change, they kick, they scream, they pout and cry. Play enough board games and there's every chance you'll become one of those people who's eye's light up at the prospect of change.
In real life, change can often suck. It brings with it risk and insecurity. But if you've been playing board games (not monopoly) on a regular basis, you'll have learned to adapt to changes and to deal with them, perhaps only on a recreational level but it's something; it's a foundation on which you'll become more mentally robust and it's something you'll build upon.
4) They stay happy
This is probably the most infuriating point on the info-graphic as expressed by /u/R-frank_undershaft who exclaims "Well fuck. If only I had known it were that simple."
Board games will help you stay happy (not monopoly though).
See there's a reason I'm telling you to play board games not computer games. Board games sit you in front of real people. They encourage you to invite your friends and family over and engage and interact in new and wonderful ways. They're a socially enriching and communally enjoyable experience that forges bonds between the participants in unique ways and I'll go so far as to say they enhance relationships between friends and families. They're a shared event that when enjoyed regularly, no doubt help fortify all the pillars of happiness.
5) They are kind
If you're someone for whom kindness does not come easy, then why not try a board game (definitely not monopoly though)? In a board game acts of kindness and mercy come at very little actual cost. They can even be a useful tool in manipulating your opponents into alliances or truces. A kindness from you early on could be enough to sway an opponent to launch his assault on someone else?
It's not all kindness for strategic gain though. While a 'kind' player will generally perform better than a 'mean' player in most games, board games are obviously a social experience as much as they are a ruthlessly strategic one and all sorts of altruistic behavior can be observed and learned.
Perhaps your friend made a strategic blunder and would like to change something he did on his turn? You could let him, it's only a game. Perhaps a rule misinterpretation has unbalanced the game, now you all have to discuss and arrive at a fair way of readdressing things?
Board games afford for many opportunities to display kindness and because of their somewhat isolated nature, you'll be able to see the effects of that kindness play out and come back on you; hopefully encouraging you to greater acts of kindness and altruism in the world proper.
6) They are willing to take calculated risks
Board games are all about calculated risks (not monopoly though). Rare is the game where all your moves will have a perfectly predictable outcome. You may have some idea of what your opponents will do or what card will come up next, but you'll rarely be sure. So instead you'll calculate the risks, weigh the benefits, assess the possibilities.
Again, the more board games you play, the more competent you'll become at this and the more likely you'll be to extract these thought processes into your day to day life. Which no doubt is full of significantly less certainties than even the most volatile of board games..
7) They invest their energy in the present
Playing board games will teach you the importance of the present moment. Last turn has been and gone, what happened happened and it can't be taken back. Board games encourage you to be mindful of the past and plan for the future, but they ground you in the present by forcing you into a spot light and saying "it's your turn..." The things that have happened and the things you want to happen melt away as you're confronted with "what are you going to do now"...
A wiser man than me says that the vast majority of mental suffering comes from people living either in the future or in the past. While playing board games you'll learn it's useful to be mindful of the past and future, but it's in the present you must live and act. playing board games regularly, can teach you the importance of focusing on the present. By seeing the consequences of fixating on the past or the future play out in a game, you'll be more likely to identify when you're doing it in life. You'll begin to understand how fleeting the past is, how changeable the future is and how important right now is.
Apart from if you're playing monopoly. You'll learn nothing if you play monopoly.
8) They accept full responsibility for their past behavior
If you shy away from owning your actions at the moment, a regular board game evening could cure you fast. By condensing the rise and fall of empires into an evening of play on a tabletop, accountability becomes something you can't escape. Everybody saw you go back on your word and march on your neighbor, there's no denying it and to do anything less than owning your actions will foster nothing but more mistrust and resentment.
Accepting responsibility in board games is unavoidable (apart from in monopoly) and learning to do it for something as trivial as a game will help you recognize those moments in life when you have the opportunities to take responsibility and it will hopefully give you insight into the effects of doing so and the repercussions of not.
9) They celebrate other peoples success.
Unlike in life, in board games there are nearly always clear winners (not in monopoly though). If you play a good variety of games regularly, with a lot of different people; you'll find yourself almost commonly in a situation where despite your best efforts, you've lost and someone else has won.
Now it's only a game, played out over an evening so it's not difficult to be respectful and congratulatory to the victor. Over enough evenings and enough games though, you could find what was once a reluctant pleasantry has turned into a genuine feeling of respect and admiration. Seeing someone win and win well in a way you didn't see coming can be impressive and what's more, there's always something to be learned in another players victory.
Over time it's possible you could begin looking at peoples success in life in the same way. By celebrating other peoples success you're more likely to examine it, to learn it's lessons.
Now I'm only halfway through the points on the info-graphic but I'm approaching both my character limit and my bed time so I'll close out with a tldr; and maybe someone else can finish explaining how the other points are applicable or perhaps if anyone made it this far you should pop over to /r/boardgames and get started?
TLDR; Playing board games (with the exception of monopoly) will help make you more mentally robust...
