The easiest person to deceive is yourself.

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. 

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

Shoot for the moon and even if you miss you’ll land among the stars/

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

Nobody said it’d be easy, they just promised it would be worth it.

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

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

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

There are no bad mistakes in maths, only discoveries.

Everything you want is on the other side of fear

A book a day keeps the stupidity away.

The greatest mistake we make is living in constant fear that we will make one.

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

Time is your friend, impulse is your enemy.
