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. 

You cannot escape the responsibility of tomorrow by evading it today

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.

I think, therefore I am.

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

Time is your friend, impulse is your enemy.

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

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

Failure to prepare = preparing to fail

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

Just stick with it, what seems hard now will one day be your warm up.

The journey of a thousand miles begins with one step. 

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.
