The journey of a thousand miles begins with one step. 

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. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

We are all maths people : step 1 - do maths and step 2 - be a person. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

Hard work beats talent when talent doesn't work hard.

The journey of a thousand miles begins with one step.

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

You cannot escape the responsibility of tomorrow by evading it today

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

No one starts out on top. You have to work your way up.

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

Tough times never last, but tough people do.

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