If you want to succeed, double your failure rate.

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.

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

The temptation to quit will be the greatest when you are about to succeed

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. 

Tomorrow is worth more than yesterday but less than today.

Everything that happens was once a dream.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

The journey of a thousand miles begins with one step. 

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

We learn more from failure than we do from success.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Dreams don't work unless you do.

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

You can have results or excuses, not both
