No matter how bad it gets, you’re still way ahead of those who haven’t even started.

I think, therefore I am.

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

Procrastination makes easy things hard and hard things harder.

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.

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

We all have two lives. The second begins when we realise we only have one. 

The wise person knows that no answer is also an answer

We learn more from failure than we do from success.

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. 

Your attitude is everything. Pick a good one.
