The greatest mistake we make is living in constant fear that we will make one.

Run in the morning before your body figures out what you're doing

Success is a journey, not a destination.

It is never too late to turn an unproductive day into a productive one.

It doesn’t matter where you start, it matters how you end

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

There are no shortcuts to any place worth going.

The master has failed more times than the beginner has even tried

Failure to prepare = preparing to fail

The journey of a thousand miles begins with one step. 

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

He who has begun his task is half-way done. Have the courage to begin!
