I can is 100 times more important than IQ.

The temptation to quit will be the greatest when you are about to succeed

Success is a journey, not a destination.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Skills are built not born.

The road to success is like a staircase. If you want to succeed, double your failure rate

Dreams don't work unless you do.
