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

Fall down seven times, stand up eight.

GCSE and A Level Maths are a marathon not a sprint

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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.

Failure is not the opposite of success, it is part of the success.

The wise person knows that no answer is also an answer

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

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.
