Faith is confidence or trust in a person or thing. It can also be interpreted as loyalty and fidelity in a strong belief. In terms of spirituality, it is a belief in one's religious doctrine (i.e. Christian faith, Jewish faith, Muslim faith, Buddhism, etc.). In terms of my Christian faith, it means supreme belief and trust in God. And as Dr. Martin Luther King Jr. famously said, "Faith is taking the first step even when you can't see the whole staircase." Personally, I believe there are tenets one must live by to possess complete faith.
Belief: Hebrews 11:1 says, "Faith is the substance of things hoped for and the evidence of things unseen." Simply put, if you don't sincerely believe in your dream, you'll never reach it. True belief is knowing beyond a shadow of a doubt your dream is real, it's yours, and no one or nothing will stop you from reaching it. But belief, in and of itself, can't make the dream real--you must also work for it.
Work: James 2:20 "For as the body without the spirit is dead, so faith without works is dead also."
You have to work diligently and tirelessly for your dream. How bad do you really want it? You must do the work--there aren't any shortcuts. And honestly, you shouldn't want to take any shortcuts in the first place. That's not how this works. For example: Wanting to become a writer on belief alone won't make you one. You have to learn, research, take courses, etc., but even then, you must expect your dream to come true.
Expectations: Hebrews 10:36 "For ye have need of patience, that after ye have done the will of God, ye may receive the promise." An attitude of expectation is paramount. You have to place the vision of your dream in your mind's eye and hold it there. Even while working towards it, act as if you've already achieved your dream.
Believing, working, and expecting equals a dream realized instead of a hope or wish on its own that's sure to die.
