Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Don’t practice until you get it right, practice until you can’t get it wrong.

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

The greatest enemy to human potential is your comfort zone

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

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Go as far as you can see, when you get there, you’ll be able to see further

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

The temptation to quit will be the greatest when you are about to succeed

Procrastination makes easy things hard and hard things harder.

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

The journey of a thousand miles begins with one step. 

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

It always seems impossible until it's done.
