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.

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.

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

There are no bad mistakes in maths, only discoveries.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

You can hire a tutor but you can't hire someone to practice for you.

Dreams don't work unless you do.

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

You can have results or excuses, not both

Start, struggle, fail, fix and learn. Repeat.

If you can understand just one thing thoroughly, then you will understand everything.

Time is your friend, impulse is your enemy.

Knowledge is of no value unless you put it into practice.
