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

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. 

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

Failure to prepare = preparing to fail

Time is your friend, impulse is your enemy.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.
