It always seems impossible until it's done.

Failure to prepare = preparing to fail

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. 

Knowledge is of no value unless you put it into practice.

Tomorrow is worth more than yesterday but less than today.

I can is 100 times more important than IQ.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

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

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

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

It is never too late to become what you might have been

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

Failure is not the opposite of success, it is part of the success.

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