I was talking with a professor about my work on the bus last night and mentioned that having faith in what I'm doing is what makes me possible to do it.
He shared that he's a born-again Christian and he's thought about faith is important in what he does, since you've never got any guarantee that a research project is going to be successful.
I'm a pagan, so I like the Japanese word "Haruhi" which means "full of spirit." (It's been popularized in the U.S. by a post-modern recent anime which I can't decide if I like or not.) But it's an important thing. For the idea I'm working on, I find that being "Haruhi" makes me invincible... I used to be a terribly anxious person but I believe in what I'm doing so much that nothing bothers me.
Quite funny, my business plan from the very beginning assumed that the system I was building would soon become more than the sum of it's parts, but I was quite amazed to see it happen... For me it's a miracle.
