Most faiths should have enough literature to answer that themselves. I live out my faith by sticking to what I believe in, Christianity, with a optimistic attitude that is rooted in reality.
prayer and faith lead me to use good judgment, have compassion to help other people, try to be pleasing and obedient to God, ask for his help in all actions or decisions I made
Faith is the "FUEL" that propels People in life, You can have faith in many different things, some people its money, some its power, some religion, to many things to list, but you get the idea.
