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.
Impossible is a word to be found only in the dictionary of fools!
Never let the fear of striking out keep you from playing the game!
I believe that if you'll just stand up and go, life will open up for you. Something just motivates you to keep moving.
Talent is cheaper than table salt. What separates the talented individual from the successful one is a lot of hard work.
If you fell down yesterday, stand up today!
