It's always too early to quit.
The harder I work, the luckier I am.
Knowing is not enough; we must apply. Willing is not enough; we must do.
One that would have the fruit must climb the tree.
You get the best out of others when you give the best of yourself.
We aim above the mark to hit the mark.
Efficiency is intelligent laziness.
It is no use saying, "We are doing our best." You have got to succeed in doing what is necessary.
It's the constant and determined effort that breaks down resistance, sweeps away all obstacles.
There are no shortcuts to any place worth going.
