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. 

You're not in competition with anyone but yourself. Outdo your past, not other people.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Run in the morning before your body figures out what you're doing

Your limitation - its only your imagination.

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

Tough times never last, but tough people do.

Failure to prepare = preparing to fail

The easiest person to deceive is yourself.

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

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

Start, struggle, fail, fix and learn. Repeat.

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

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

Time is your friend, impulse is your enemy.
