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

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

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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. 

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

I have not failed, I've just found 10,000 ways that won't work.

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

Just stick with it, what seems hard now will one day be your warm up.

The greatest enemy to human potential is your comfort zone

Do what you have always done and you will always be what you have always been

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.
