The best you can hope for in this life
is that your delusions are benign
and your compulsions have utility.
It comes from an equally insightful blog post from the creator of the dilbert cartoons, Scott Adams, and was posted by @lmg, whom I follow because he's the hero of this story.
If I ever write up "my philosophy", this quote will have its own chapter. And maybe I can print my own greeting cards with an edited version, such as:
May all your delusions be benign
and your compulsions useful ones.
I am, of course, a compulsive writer and under the delusion that people want to read what I have to say, and I am very grateful that my delusion is relatively harmless and my compulsion just about useful enough to pay the bills.
