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 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 can have results or excuses, not both

In order to become better than anybody else you must first become better than yourself.

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

The wise person knows that no answer is also an answer

Instead of finding reasons why you can't, find reasons why you can.

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

Your attitude is everything. Pick a good one.

Your limitation - its only your imagination.

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