One of my bosses quit Microsoft in the late 80s, right before the company exploded. Your mistake isn't as big as that. I tried to make my own startup for years in my 20s, making nothing for years. My salary is so far behind (hopefully not for long) and I could've FIREd by now if I'd just worked at regular tech companies. I just get angry at myself every few weeks but try not to think about it the rest of the time.
