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. 

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

We all make mistakes. What matters is how we choose to move forwards from them.

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

We learn more from failure than we do from success.

You cannot escape the responsibility of tomorrow by evading it today

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 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 fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

There are no shortcuts to any place worth going.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

No one starts out on top. You have to work your way up.

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

The journey of a thousand miles begins with one step.
