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 think, therefore I am.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Failure to prepare = preparing to fail

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.

Procrastination makes easy things hard and hard things harder.

You cannot escape the responsibility of tomorrow by evading it today

The bad news is time flies, the good new is that you're the pilot.

Skills are built not born.

Hard work - a two way street where you get exactly what you put in.

There are no bad mistakes in maths, only discoveries.

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

Everything you want is on the other side of fear

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Time is your friend, impulse is your enemy.
