What have you always wanted to do but been afraid to attempt? Whatever it is, it may be your greatest opportunity in life.
Your persistence is your belief in yourself.
There are no unrealistic goals, only unrealistic deadlines.
Success is goals, everything else is commentary.
So many people spend so much time on things that aren't important. It's the difference between success and failure.
Resolve in advance to persist until you succeed, no matter what the difficulty.
