Just stick with it, what seems hard now will one day be your warm up.

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

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. 

I think, therefore I am.

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.

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

Tomorrow is worth more than yesterday but less than today.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Everything you want is on the other side of fear

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

Dreams don't work unless you do.

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

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