I can is 100 times more important than IQ.

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

Time is your friend, impulse is your enemy.

We all make mistakes. What matters is how we choose to move forwards from them.

The greatest enemy to human potential is your comfort zone

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

There are no bad mistakes in maths, only discoveries.

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. 

It doesn’t matter where you start, it matters how you end

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
