Failure is not the opposite of success, it is part of the success.

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

A book a day keeps the stupidity away.

Instead of finding reasons why you can't, find reasons why you can.

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

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

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. 

Time is your friend, impulse is your enemy.

Everything you want is on the other side of fear

The master has failed more times than the beginner has even tried

I can is 100 times more important than IQ.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

You can have results or excuses, not both

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.
