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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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.

Never underestimate the importance of small steps. small steps = big changes. 

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.

He who has begun his task is half-way done. Have the courage to begin!

Do what you have always done and you will always be what you have always been

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 hang your targets after you’re done shooting.

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

99% of failures come from people who have the habit of making excuses.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

We learn more from failure than we do from success.
