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

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 bad news is time flies, the good new is that you're the pilot.

"I" not them. Be the best version of you.

Fall down seven times, stand up eight.

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

The master has failed more times than the beginner has even tried

Skills are built not born.

Never underestimate the importance of small steps. small steps = big changes. 

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

Hard work beats talent when talent doesn't work hard.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Failure to prepare = preparing to fail

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