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.

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

You cannot escape the responsibility of tomorrow by evading it today

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

The temptation to quit will be the greatest when you are about to succeed

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

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

Success is a journey, not a destination.

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

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

Skills are built not born.

Everything you want is on the other side of fear

"I" not them. Be the best version of you.

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

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