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. 

There is no elevator to success, you have to take the stairs.

It doesn’t matter where you start, it matters how you end

In order to become better than anybody else you must first become better than yourself.

Success is not final and failure is not fatal. It is the courage to continue that counts.

You cannot escape the responsibility of tomorrow by evading it today

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

We all have two lives. The second begins when we realise we only have one. 

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Time is your friend, impulse is your enemy.

Failure is NOT your destiny. Failure is the key to success.

The journey of a thousand miles begins with one step.

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

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

The easiest person to deceive is yourself.
