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. 

Success is the sum of small repeated efforts, day in and day out.

Skills are built not born.

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

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

Success is a journey, not a destination.

The wise person knows that no answer is also an answer

The journey of a thousand miles begins with one step. 

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Run in the morning before your body figures out what you're doing

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

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

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

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