Belief is a powerful thing once you master it.
Try something, belief comes a little bit, try again it comes some more.
It is a self-fulfilling thing, but you have to overcome fear and start. If you never start, you’ll never believe, but be patient, it does not come all at once.
Once you start, you have to keep going, step by step, day by day.
Finally, ignore others, as the people who will love what you do will believe when you do, they’re the people who matter and others simply don’t matter.
Try, try, try and try, belief comes stronger at every step.
