Your solution to feeling socially isolated, having no fulfilling hobbies outside of work, and your apparent unhappiness, despite your success, is to open a co-working space?
Folks, this is as clear as an indictment of the culture as you get.
I work out of a co-working space. They're great. I am slowly working my way up the informal foosball rankings. And I'm not particularly good at living life, but we're still working at the financial stability part.
There is more to life than work, even if you were blessed with huge natural reservoirs of motivation. Learn to paint. Learn to cook. Learn another language. Write fiction, investigate some non-fiction, learn how to take beautiful photographs (pro-tip: your iPhone is an amazing camera), READ BOOKS, start playing a team sport in an adult rec league, go camping, if you can afford it GO TRAVELLING, oh my god you have the money and total flex but you won't go travelling?, VOLUNTEER at the homeless shelter, at the library, at the office of a political cause you believe in, INTERACT WITH OTHER HUMAN BEINGS [in a setting outside of "lol tech startups" once in a while].
