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. 

The road to success is like a staircase. If you want to succeed, double your failure rate

A hero is no braver than an ordinary man, but he is braver five minutes longer.

The journey of a thousand miles begins with one step. 

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

Knowledge is of no value unless you put it into practice.

If you want to succeed, double your failure rate.

If you fail, next time fail better.

Procrastination is the thief of time and the enemy of success.

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.

Don't fear failure, fear being in the same exact same place next year as you are now.

The power of reflection is the most powerful skill you’ll learn.

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

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