Procrastination is the thief of time and the enemy of success.

Dreams don't work unless you do.

There are no shortcuts to any place worth going.

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. 

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Success is a journey, not a destination.

The journey of a thousand miles begins with one step. 

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.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

I think, therefore I am.

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

Run in the morning before your body figures out what you're doing

Everything you want is on the other side of fear
