My father used to, and probably still does, have this list in his bathroom in Surry:

The Three Grand Essentials of Happiness

1. Something to do
2. Someone (or something) to love
3. Something to look forward to

I just noticed this next to my grandfather’s computer:

Stroke!

1. Smile
2. Raise both arms
3. Speak a simple sentence

I find humor in that searching for “lists of threes” on google, the first link is a discussion of how in presentations you should do things in three’s because people tend to remember that number better. Yet the page lists four points.
