"I" not them. Be the best version of you.

It is never too late to turn an unproductive day into a productive one.

There is no elevator to success, you have to take the stairs.

Time is your friend, impulse is your enemy.

I can is 100 times more important than IQ.

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

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

Success is the sum of small repeated efforts, day in and day out.

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. 

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

Skills are built not born.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.
