You can be shown the path, but only you can make the first step.

You're not in competition with anyone but yourself. Outdo your past, not other people.

The easiest person to deceive is yourself.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

There is no elevator to success, you have to take the stairs.

The greatest enemy to human potential is your comfort zone

Success can never happen without the journey (struggle).

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

There are no shortcuts to any place worth going.

The power of reflection is the most powerful skill you’ll learn.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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. 

You cannot escape the responsibility of tomorrow by evading it today

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.
