Faith & Belief & Expectancy

I was just looking at some more Law of Attraction material, and I realized that faith, belief, expectancy, etc all are natural. You don't have to do anything to facilitate them; just stay focused on what you want, you'll attract more thoughts of it, so, and so on(you already know that). What really is the problem is your disbelief when you think of things like how it's going to come about. All that I'm saying is basic info, but I really wanted to type all this up because I originally though that I had to build up my faith.
