Failure to prepare = preparing to fail

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.

Pure mathematics is in its way, the poetry of logical ideas.

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

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 master has failed more times than the beginner has even tried

The journey of a thousand miles begins with one step.

You cannot escape the responsibility of tomorrow by evading it today

I have not failed, I've just found 10,000 ways that won't work.

The bad news is time flies, the good new is that you're the pilot.

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

There are no shortcuts to any place worth going.

Fall down seven times, stand up eight.

I think, therefore I am.
