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. 

There are no shortcuts to any place worth going.

We learn more from failure than we do from success.

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

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

I can is 100 times more important than IQ.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Success can never happen without the journey (struggle).

Everything you want is on the other side of fear

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.
