Great question, I wish I had an true problem statement so I could then work towards solving that problem. I work on myself a lot; it's probably the one thing I focus on most. Mostly because I'm not as happy as I could be.
I've become a little bit of a shut in because of two factors. 1) video games are cheap and cost effective. 2) in my early relationships (age 15-23) I had dated some manipulative women and haven't had any fruitful relationships since. Because of this I am kind of untrusting, and a lot of social media premotes a 'grass is greener' mentality. I as an individual can't compete with that.
I went through a shitty person phase where I drank too much and wasn't a thoughtful or considerate person. For example, my high school friends wanted to kick me out of the 4bedroom house because I was alcoholic and aggressive. I couldn't make rent one month because I'd left an open tab at a bar and the bill ate I to my rent money. It was a big problem and strained one of my most important friendships. Looking back it's a regrettable time in my life. It highlighted a "Yosemite Sam" complex where I wanted to fight people for whatever reason and looking back at it that was stupiy. I'm not a big guy or a tough guy, so working through that complex became a priority.
From age 30-2ish onwards I started living on my own after acknowledging/self-vocalizing some of my short comings I had some targets for self betterment: Cleanliness, working out, drinking less. My secret is (to this day) I still think I'm a piece of garbage, and I motivate myself to do things because of that.
Around the age of 33 I was gaming with my cousin (best friend in the whole wide world,#1 bro) and his shit talking got too personal and cut too deep, (I'd had 2/3 a bottle of Tito's & some OJ), was so offended personally attacked (the way he only knows how to do) and I very-drunkenly drove to his house and attempted to call him out and scrap. My cousin is twice my size, I'm 5'7" 155lbs, he's 6'2. I got to his place and started shouting, his wife came out and told me to go. I should've never been behind the wheel. I haven't seen him since. We had a couple latent phone calls after that event, he strongly suggested I find a therapist and work out my issues.
aside from the personal attack and offence, my cousin's relationship meant so much to me and repairing that became the priority. So I found a therapist, we've met twice a month since the spring of 2017 and I've had so much progress. We talk about everything from family, romance, career plans and everything in between. To my credit, and the guidance/affirmation from my therapist, I've grown so much. I completed a degree in C# development and after a few consulting (contact) roles have reached my goal of a six figure salary(as fte). I've done a lot of work to better myself in career and in general knowledge. In a year and a half I went from 60k to 105k and the current team and boss and so cool, I couldn't be happier (I've been there 8 months).
I do a gym work out 3 to times a week at minimum. I'm not a crazy gym goer or cross-fire type but work out regularly to stay in good shape. I cycle in the spring and love beach volleyball/ultimate Frisbee.
I'm 35 now and over the last 7 years I've turned myself from a dirt bag with drinking problems to a person who has grown out of the "Yosemite Sam complex" because 99.99% aggression doesn't solve anything.
I'm sure there's a lot of context I'm leaving out. I think I've been successful at cultivating my self as a well rounded adult. I'm probably afraid of intimacy but absolutely want to find a "partner in crime" to tackle the world with.
So I don't know why I'm single, I've had so much growth in the last few years, I meet women and am not afraid to get their numbers but never make a second date make some reason that I think the wouldn't be a good match. Probably over critical.
Even after all this personal work I'm realizing I'm afraid some pretty lady will year it all down. It's probably a trust issue, sadly.
