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

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

If you can understand just one thing thoroughly, then you will understand everything.

Practice like you’ve never won. Perform like you’ve never lost.

Knowledge is of no value unless you put it into practice.

Fall down seven times, stand up eight.

Procrastination is the thief of time and the enemy of success.

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

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

You can have results or excuses, not both

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

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

Just stick with it, what seems hard now will one day be your warm up.

Procrastination makes easy things hard and hard things harder.
