"Don't measure yourself by what you have accomplished, but by what you should have accomplished with your ability."
Only you know the truth about what you accomplished or will accomplish today: Is it the best you could have done with the abilities you have? Or is it something less than that? We cannot be our best every day for dozens of possible reasons and obstacles. However, we can choose today to be our best in every possible moment. To do less is to be less. What will you choose today?
