The greatest enemy to human potential is your comfort zone

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

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

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

Success can never happen without the journey (struggle).

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

If you want to succeed, double your failure rate.

Procrastination makes easy things hard and hard things harder.

The journey of a thousand miles begins with one step.

Lose an hour in the morning and you will spend all day looking for it.

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

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

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.

Fall down seven times, stand up eight.

Success is not final and failure is not fatal. It is the courage to continue that counts.
