I haven't done much searching into what makes the world work. I've heard things and I've considered them and I've inserted some of them into my belief. What I have done is examined how to work the world. I use my beliefs and understanding to better my quality of life. And it works! My belief, whilst filled with ideas, can be summarised into one quote from Dogma:

"It doesn't matter what you have faith in, so long as you have faith!"
- Serendipity, Dogma

I have faith in myself. I think "I can't do that!" Then I think "Why not?" With faith in yourself you can remove fear. Without fear you have more confidence. With more confidence, the more likely you are to succede.
