I just read through it all and realized you're just 23! I don't think you should be so hard on yourself. I thought you were like 40 and lost with no hope. But at 23? Come on.... Just get yourself a simple job for a bit. Take a break. What do you have to lose? Once you sound a little less burned out, you can give startups a shot again. Have some patience, and please enjoy your journey; you only get to do it once.
I had the same reaction as you and I did a search for 23 in this thread and nobody else is talking about this. Has Zuckerberg really skewed a generation. The odds of you making it big at the age is insanely low.
Taking 7 years to get good at something is actually a smart thing to do. The best thing to do is always look for a room where you are not the smartest so you can learn and when you can't find anymore rooms, you'll know it's your time.
