First we have to believe, and then we believe.

To believe is to become what you believe

I profoundly believe it takes a lot of practice to become a moral slob.

You have to believe. Otherwise, it will never happen.

Everything in life worth achieving requires practice. In fact, life itself is nothing more than one long practice session, an endless effort of refining our motions. When the proper mechanics of practicing are understood, the task of learning something new becomes a stress-free experience of joy and calmness, a process which settles all areas in your life and promotes proper perspective on all of life’s difficulties. — Thomas Sterner

During your whole life you practiced every moment to become what you believe you are right now. You practiced until it became automatic. And when you start practicing something new, when you change what you believe you are, your whole life is going to change. If you practice being impeccable with your word, if you don’t take anything personally, if you don’t make assumptions, you are going to break thousands of agreements that keep you trapped in the dream of hell. Very soon, what you agree to believe will become the choice of your authentic self, not the choice of the image of yourself that you thought you were.

Try, really try. Think, really think. Believe, really believe.

Knowing it — knowing it's true is one thing, but believing what you know... well, there's the tough part.

And belief is a choice. It is simply a thought you choose to think over and over until it becomes automatic.

The belief in a thing makes it happen.

You must believe in what you're doing, that what you're doing is the proper thing, the right thing. And you must have faith that things will end up as they should, which doesn't mean as you want them to, but things will work out as they should.
