10 years of failure

I guess a rant as well as seeking advice. I started my first company at the age of 22 right out of college. It was semi successful. Scaled it to a few crore in revenue but because of some issues had to close it down. Worked on a few products again which again did alright but not enough to giving me savings. This experience ranged from software to e-commerce. Building different products. I’m now 31, and started a biotech company about a year back. However stuff has been slow. I’ve barely any savings and funding in my space is scare. So it’s been small government grants. I’ve realised that if this doesn’t take off, after 10 years of struggle I probably need to look for a job atleast for a few years. (Won’t ever give up on starting up. I’m a fighter that way.) My resume is eclectic. I’ve done all sorts of stuff with mediocre success. But don’t have a defined skillset. (Like being a programmer for example). I guess one skillset I can say I have is identify and opportunity. Also I have tremendous stress tolerance and ability to work. What should I do? Should I eventually look for a job? If yes, honestly I don’t even know what job profile I’ll go for. Because I’ve never done a job ever. I’m confused. I’m not married and don’t plan to. For me me, running a company is everything and I’m willing to sacrifice everything else for it. (Includes not being married so that I don’t have pressure to maintain the lifestyle married life entails.) Sorry for the long post. Also great respect to you guys who’ve made it :) and also to the once struggling. It’s us who keep the economy ticking at great personal cost of health and finance. Fighters.
