"Challenges are what make life interesting and overcoming them is what makes life meaningful.."
"Even if you're on the right track, you'll get run over if you just sit there.."
"The only way of discovering the limits of the possible is to venture a little way past them into the impossible.."
"Perseverance is the hard work that you do after you get tired of doing the hard work that you already did.."
"Only the wise man, only he whose thoughts are controlled and purified makes the winds and storms of life obey him.."
"Opportunity is missed by most people because it is dressed in overalls and looks like work.."
"Be great in act, as you have been in thought."
"In order to succeed, your desire for success should be greater than your fear of failure.."
