No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

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

Try and do one thing each day that you would really rather not do.

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

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

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

There are no bad mistakes in maths, only discoveries.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

I think, therefore I am.

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

Don't fear failure, fear being in the same exact same place next year as you are now.
