If people are doubting how far you can go, go so far that you can't hear them anymore.
You're not obligated to win. You're obligated to keep trying to do the best you can every day.
There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits!
Nothing ever comes to one, that is worth having, except as a result of hard work!
Do not whine. Do not complain. Work harder.
Obstacles can't stop you. Problems can't stop you. Most of all, other people can't stop you. Only you can stop you.
Let me tell you the secret that has led me to my goals: my strength lies solely in my tenacity.
Motivation will almost always beat mere talent.
If you get tired, learn to rest, not to quit.
A little more persistence, a little more effort and what seemed hopeless failure may turn to glorious success.
