Lose an hour in the morning and you will spend all day looking for it.

In order to become better than anybody else you must first become better than yourself.

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

We all have two lives. The second begins when we realise we only have one. 

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

It always seems impossible until it's done.

The power of reflection is the most powerful skill you’ll learn.

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

Tomorrow is worth more than yesterday but less than today.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

Success is the sum of small repeated efforts, day in and day out.

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

We learn more from failure than we do from success.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
