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

Everything you want is on the other side of fear

Nobody said it’d be easy, they just promised it would be worth it.

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

Skills are built not born.

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

Success is the sum of small repeated efforts, day in and day out.

The wise person knows that no answer is also an answer

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. 

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.

A book a day keeps the stupidity away.

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.

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

Time is your friend, impulse is your enemy.

Your limitation - its only your imagination.
