Tomorrow is worth more than yesterday but less than today.

The greatest mistake we make is living in constant fear that we will make one.

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. 

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

You can have results or excuses, not both

If you want to succeed, double your failure rate.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

The wise person knows that no answer is also an answer

Your attitude is everything. Pick a good one.
