There are no bad mistakes in maths, only discoveries.

It is never too late to turn an unproductive day into a productive one.

We learn more from failure than we do from success.

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

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

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.

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

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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

Dreams don't work unless you do.

Life is full of opportunities. With every opportunity that is missed, another one is born.

We are all maths people : step 1 - do maths and step 2 - be a person. 

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. 

A book a day keeps the stupidity away.
