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

Time is your friend, impulse is your enemy.

There is no elevator to success, you have to take the stairs.

I have not failed, I've just found 10,000 ways that won't work.

The journey of a thousand miles begins with one step. 

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

No one starts out on top. You have to work your way up.

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.

There are no bad mistakes in maths, only discoveries.

You cannot escape the responsibility of tomorrow by evading it today

Mistakes have the power to turn you into something better than you were before.

Failure is NOT your destiny. Failure is the key to success.

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

Your limitation - its only your imagination.
