You are a piece of the puzzle of someone else's life
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 more you believed in yourself the more you could trust yourself. The more you trust yourself the less you compare yourself to others.
Pride is holding your head up when everyone around you has theirs bowed. Courage is what makes you do it.
You have to believe in yourself challenge yourself and push yourself until the very end; that's the only way you'll succeed.
The only person who can pull me down is myself and I'm not going to let myself pull me down anymore.
Believe in yourself and the rest will fall into place. Have faith in your own abilities work hard and there is nothing you cannot accomplish.
