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. 

He who has begun his task is half-way done. Have the courage to begin!

The journey of a thousand miles begins with one step. 

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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

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

Failure is not the opposite of success, it is part of the success.

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

If you fail, next time fail better.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Success is a journey, not a destination.

Tough times never last, but tough people do.

There are no shortcuts to any place worth going.

Everything that happens was once a dream.
