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. 

Success is a journey, not a destination.

Never underestimate the importance of small steps. small steps = big changes. 

I think, therefore I am.

Procrastination makes easy things hard and hard things harder.

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

I can is 100 times more important than IQ.

You can be shown the path, but only you can make the first step.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

FAIL - First Attempt In Learning

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

The road to success is like a staircase. If you want to succeed, double your failure rate

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

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

We learn more from failure than we do from success.
