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

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

We all make mistakes. What matters is how we choose to move forwards from them.

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

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

Tough times never last, but tough people do.

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. 

Procrastination makes easy things hard and hard things harder.

Dreams don't work unless you do.

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

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.

Hard work beats talent when talent doesn't work hard.

Success is a journey, not a destination.

Don't fear failure, fear being in the same exact same place next year as you are now.
