The Four Most Difficult Overcomings

If the distance between what you are and what you wish to be matters more to you than the distance between what you are feeling at this moment and what you would like to be feeling at this moment, then you are no longer a child.

If the distance between what you are doing and what you wish to be doing matters more to you than the distance between what you are doing and what others want you to be doing, then you are an adult.

If the distance between what you know and what you wish you knew matters more to you than the distance between what you think and what others expect you to think, then you are a properly civilized adult.

If the distance between what you believe and what is true matters more to you than the distance between what you believe and what would be most comfortable for you to believe, then you are a philosopher.
