I think the reason you failed is because what you really care about is writing? The story is good and you should stick to that.
Nobody cares.. I think the failedtrader gig is taken. I think your problem is you go around calling yourself a loser. Your first step should be to change that. That means a new name and new blog... ciao
Then maybe you should not mentor anyone else since you suck at teaching. Anyone who I have helped has succeeded. I use a set of rules that work most of the time. If I break my rules, I usually lose on the trade.
Anything is possible with time and discipline, keep your chin up, you'll cop a few knocks now and then but if you don't give up who knows where the journey may take you.
