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.

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

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

No one starts out on top. You have to work your way up.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

There are no bad mistakes in maths, only discoveries.

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

Tough times never last, but tough people do.

He who has begun his task is half-way done. Have the courage to begin!

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

Success can never happen without the journey (struggle).

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

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

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