Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

The easiest person to deceive is yourself.

Do what you have always done and you will always be what you have always been

We learn more from failure than we do from success.

I think, therefore I am.

Never underestimate the importance of small steps. small steps = big changes. 

Skills are built not born.

Shoot for the moon and even if you miss you’ll land among the stars/

Everything you want is on the other side of fear

It is never too late to become what you might have been

You cannot escape the responsibility of tomorrow by evading it today

You can be shown the path, but only you can make the first step.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
