The easiest person to deceive is yourself.

If you want to succeed, double your failure rate.

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

We all have two lives. The second begins when we realise we only have one. 

The wise person knows that no answer is also an answer

If you fail, next time fail better.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

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. 

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

Success can never happen without the journey (struggle).

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

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