There are no bad mistakes in maths, only discoveries.

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

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

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

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

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

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

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

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

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

There are no shortcuts to any place worth going.

We learn more from failure than we do from success.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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.
