If you can understand just one thing thoroughly, then you will understand everything.

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

Your attitude is everything. Pick a good one.

Shoot for the moon and even if you miss you’ll land among the stars/

Success can never happen without the journey (struggle).

Failure is NOT your destiny. Failure is the key to success.

Hope might be a good breakfast, but it makes a very poor dinner

Don’t hang your targets after you’re done shooting.

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

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

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

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. 

Tomorrow is worth more than yesterday but less than today.

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

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