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

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

You cannot start the next chapter of your life if you keep re-reading the last one.

Everything you want is on the other side of fear

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

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

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Skills are built not born.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

It always seems impossible until it's done.

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