Interesting questions; The truth is that on a personal level I think that I always do what I like, and what I am passionate about, therefore, I am not thinking about failing or succeeding. Although I want to be financially successful (and I need to make money, like everyone else), it's not my main focus in everything I do; because if it were so, my anguish would be very great.

What would I do if I knew that what I am doing now will fail irretrievably? I would look for other means to move forward. Failing or succeeding, surely, as you say, I would learn a lot along the way.
