There are no bad mistakes in maths, only discoveries.

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

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

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

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. 

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Failure is NOT your destiny. Failure is the key to success.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

If you want to succeed, double your failure rate.

In order to become better than anybody else you must first become better than yourself.

Pure mathematics is in its way, the poetry of logical ideas.

Dreams don't work unless you do.

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

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

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