Never underestimate the value of one percent. One percent may sound negligible, but it isn’t. On a genetic level, we humans are only about one percent different from chimpanzees.
If you were 99% happy, and just 1% sad, would you be satisfied with this result? If you were 99% well, and just 1% ill, would this be acceptable? Suppose a person were 99% sane and just 1% insane, would this be a safe ratio? I suggest the answer to all three of these questions is no.
One percent of your life is about fifteen minutes each day.
Fifteen minutes of daily sadness, illness or insanity is far too much to be considered satisfactory, acceptable and safe.
