We learn more from failure than we do from success.

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

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

The master has failed more times than the beginner has even tried

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. Rome wasn't built in a day, but they worked on it every single day. 

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

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

Procrastination makes easy things hard and hard things harder.

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.

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

Time is your friend, impulse is your enemy.

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