Whenever you find yourself doubting how far you can go, just remember how far you have come.

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. 

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

Failure is NOT your destiny. Failure is the key to success.

Lose an hour in the morning and you will spend all day looking for it.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

The greatest enemy to human potential is your comfort zone

We learn more from failure than we do from success.

Time is your friend, impulse is your enemy.

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

Success is a journey, not a destination.

I can is 100 times more important than IQ.

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

Success can never happen without the journey (struggle).

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.
