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

Don't fear failure, fear being in the same exact same place next year as you are now.

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.

I think, therefore I am.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

Everything that happens was once a dream.

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

In order to become better than anybody else you must first become better than yourself.

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. 

You can have results or excuses, not both

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

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

Hard work - a two way street where you get exactly what you put in.

If you want to succeed, double your failure rate.
