This first step is a critical part of your growth as a photographer. It's where you tune out your inner-critic and start thinking positively.
The author Norman Vincent Peale said "Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy." The transformation your thoughts can make is truly remarkable. Be careful though, negative patterns will try to creep back in. Squash them as they arise and replace it with something positive about yourself.
