There are no bad mistakes in maths, only discoveries.

There is no elevator to success, you have to take the stairs.

Skills are built not born.

There are no shortcuts to any place worth going.

Failure to prepare = preparing to fail

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. 

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

Time is your friend, impulse is your enemy.

You cannot start the next chapter of your life if you keep re-reading the last one.

Fall down seven times, stand up eight.

Just stick with it, what seems hard now will one day be your warm up.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

I think, therefore I am.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.
