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. 

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Time is your friend, impulse is your enemy.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

It is never too late to become what you might have been

If you fail, next time fail better.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

Success is a journey, not a destination.

Skills are built not born.

Do what you have always done and you will always be what you have always been

It always seems impossible until it's done.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

The journey of a thousand miles begins with one step.
