Think about why you did that, was it ONLY to become wealthy, or was there something else? Didn't you also do it because you HAD to, because it was THERE and you wanted to see it become real?
Drift about a bit, enjoy life and don't worry about stuff.. Follow what seems interesting, if that's nothing, then don't follow anything for a while and wait until something comes around that needs doing.
I've often been asked why I didn't patent FinalKey or made it into a company.. If I don't regret that because maybe I could have become wealthy. My answer is always the same: I was done with it and I had no interest in continuing it, something more interesting had come along.
