There are no shortcuts to any place worth going.

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

Procrastination makes easy things hard and hard things harder.

I think, therefore I am.

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. 

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

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

Dreams don't work unless you do.

Success is a journey, not a destination.

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

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

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

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

Failure is not the opposite of success, it is part of the success.

You cannot escape the responsibility of tomorrow by evading it today
