The greatest enemy to human potential is your comfort zone

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

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

Dreams don't work unless you do.

Failure to prepare = preparing to fail

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

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

The journey of a thousand miles begins with one step.

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

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. 

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Never underestimate the importance of small steps. small steps = big changes.
