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

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.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

I can is 100 times more important than IQ.

Tough times never last, but tough people do.

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. 

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

There are no shortcuts to any place worth going.

We learn more from failure than we do from success.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

If you can understand just one thing thoroughly, then you will understand everything.
