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

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

Dreams don't work unless you do.

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.

It is never too late to turn an unproductive day into a productive one.

You cannot escape the responsibility of tomorrow by evading it today

Procrastination is the thief of time and the enemy of success.

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

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

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

You can hire a tutor but you can't hire someone to practice for you.
