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. 

Everything you want is on the other side of fear

I can is 100 times more important than IQ.

The temptation to quit will be the greatest when you are about to succeed

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

Success is a journey, not a destination.

Time is your friend, impulse is your enemy.

Success is the sum of small repeated efforts, day in and day out.

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. The most powerful warriors are patience and time.

You cannot escape the responsibility of tomorrow by evading it today

I think, therefore I am.

The bad news is time flies, the good new is that you're the pilot.

Procrastination makes easy things hard and hard things harder.

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