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. 

You cannot escape the responsibility of tomorrow by evading it today

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

We learn more from failure than we do from success.

Don’t practice until you get it right, practice until you can’t get it wrong.

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

Practice like you’ve never won. Perform like you’ve never lost.

We learn more from failure than we do from success.

Hope might be a good breakfast, but it makes a very poor dinner

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

Everything you want is on the other side of fear

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

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

I can is 100 times more important than IQ.
