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

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

Everything you want is on the other side of fear

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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 fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

There are no shortcuts to any place worth going.

We learn more from failure than we do from success.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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

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

Tough times never last, but tough people do.

Just stick with it, what seems hard now will one day be your warm up.

The journey of a thousand miles begins with one step.
