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. 

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

Everything you want is on the other side of fear

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

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

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

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

Lose an hour in the morning and you will spend all day looking for it.

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

Don’t be afraid to work hard and find out how good you can really be.

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

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

Patience is when you’re supposed to get mad, but you choose to understand

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