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

You cannot start the next chapter of your life if you keep re-reading the last one.

Time is your friend, impulse is your enemy.

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.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

He who has begun his task is half-way done. Have the courage to begin!

We learn more from failure than we do from success.

A book a day keeps the stupidity away.

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. 

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

Start, struggle, fail, fix and learn. Repeat.

I think, therefore I am.

If you can understand just one thing thoroughly, then you will understand everything.
