Video games, typically, have a psychological model, and it looks like steps:

Work and struggle just a little bit, Get an ability yo make that pre ious struggle easy

New struggles New tools to make them easy

And so on.

Think leveling up a character, new skills, whether it's an MMO, or new weapon unlocks or mods in an FPS, or going back to previous level with uograded gear to find secrets -- it feels Good.

Games are designed that way.

There are many things in life which can Also provide this type of feel-good, and it's different for everyone.

If you have groups of friends trying new things, Say Yes. Like the Jim Carrey movie.

Sometimes the activity comes first, e.g. trying a coached strength program, and then during that program you'll quite likely make friends, and if they invite you to something, join! And if you're_ having a celebration, invite them!

Trial and error.

Snowboarding for me, a friend invited me when I was in my mid twenties. I fell all the way down the hill. Now I love snowboarding, and it's all because I said "Yes" to trying a new thing, and because my friend decided to ask, and you can be on either side of that, the invitee, or inviter.

I've been invited to many things, and tried things on my own, but Snowboarding truly stuck for me and is a reward in itself; the waxing, filing, seasoning, and tuning, is now a labor of love, I bought a mountain car to get better mileage and have better traction in the mountains, and I invite and have taught friends now too.

Point being, the reward is in itself. Just like video games. And I love me a few particular games, H:ZD, Diablo, Destiny, Warframe before the nerfed the loot a cluple years ago now.

Experiment with activities, and hopefully sooner rather than later you'll come across an activity which ceates a positive reward feedback loop for you.
