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.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

Practice like you’ve never won. Perform like you’ve never lost.

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

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Everything you want is on the other side of fear

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. 

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

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

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