Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

It doesn’t matter where you start, it matters how you end

There are no bad mistakes in maths, only discoveries.

I can is 100 times more important than IQ.

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. 

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

Success can never happen without the journey (struggle).

Procrastination makes easy things hard and hard things harder.

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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