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. 

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

We learn more from failure than we do from success.

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 practice until you get it right, practice until you can’t get it wrong.

Procrastination makes easy things hard and hard things harder.
