Winners win not because they're allowed to, but because they decide to.
Expect the best of yourself, and then do what is necessary to make it a reality.
If you focus on the obstacles, then you give them more power.
Be wary of those who seek to steal your dream. Be even more wary of those who seek to tell you what your dream should be.
Procrastinating, fighting and avoiding will only make it more difficult. The way out is to get it done.
So go ahead and face that fear, make that effort, move forward into new territory and fully live the grand possibilities with which you're blessed. Boldly face life, and you'll find it to be better than you ever imagined.
