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. 

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

Hard work - a two way street where you get exactly what you put in.

Skills are built not born.

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

Mistakes have the power to turn you into something better than you were before.

If you fail, next time fail better.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Learn To Step Outside Of Your Comfort Zone. Outside your comfort zone is where the magic happens

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

We learn more from failure than we do from success.

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

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

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