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

There are no bad mistakes in maths, only discoveries.

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. 

Procrastination makes easy things hard and hard things harder.

It always seems impossible until it's done.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

Hope might be a good breakfast, but it makes a very poor dinner

Don’t hang your targets after you’re done shooting.

The road to success is like a staircase. If you want to succeed, double your failure rate

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

Hard work beats talent when talent doesn't work hard.

Our fixed mindset builds our cage, fear keeps us in it.
