Know or listen to those who know.
The secret of getting ahead is getting started.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
It's always too early to quit.
Things do not happen. Things are made to happen.
Who seeks shall find.
To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Problems are not stop signs, they are guidelines.
The sad truth is that excellence makes people nervous.
