Don't fear failure, fear being in the same exact same place next year as you are now.

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

Patience is when you’re supposed to get mad, but you choose to understand

Do what you have always done and you will always be what you have always been

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.

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

A book a day keeps the stupidity away.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.
