Sure, I have a bunch of ideas and I have refined them. Yeah, I can write comments and get karma. I have gotten projects funded for nothing, but I would never write a bet on myself. I've just never thought myself as someone good enough for anything, but I simply try.
I know that this isn't something healthy, but it has, ironically, helped me out. I've taken risks that no sane person would take, because I always thought that I was going to lose anyway. Can you imagine a 17 y/o trying to make a dynamic haptic UI? (what the hell was I thinking?)
Sure, I have failed a lot. I have tried to run before I could crawl, but in the process I've learnt and gained far more than those who played it safe. So, maybe hopelessness in the right dose might actually be a good thing. After all what's there to lose, if you think that you have nothing to lose?
