Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Everything you want is on the other side of fear

The power of reflection is the most powerful skill you’ll learn.

Time is your friend, impulse is your enemy.

Go as far as you can see, when you get there, you’ll be able to see further

The greatest mistake we make is living in constant fear that we will make one.

It always seems impossible until it's done.

We all have two lives. The second begins when we realise we only have one. 

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

Skills are built not born.

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. The most powerful warriors are patience and time.

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

Fall down seven times, stand up eight.

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