Being an underachiever

Underachievers are the best, most dependable workers. This may seem counterintuitive but the key here is that while some achievement is necessary and good for productivity, a lot of it is dangerous to you and everyone around you. And if you have a wide enough perspective, you’ll see it’s also an exercise in futility. The assumptions underlying this statement can be found among Bennet’s “Principles of Underachievement:”
Life’s too short.
Control is an illusion.
Expectations lead to misery.
Great expectations lead to great misery.
Achievement creates expectations.
The law of diminishing returns applies everywhere.
Perfect is the enemy of good.
The tallest blade of grass is the surest to be cut.
Accomplishment is in the eye of the beholder.
