For the past few weeks, I've been thinking and writing a lot about how people of pronounced positivity and people of pronounced negativity affect each other. (a/k/a Tiggers vs. Eeyores.) These two groups often annoy and drain each other (and themselves) in their efforts to make conversions to their own ways of thinking.
Whenever I have a big idea, I try to sum it up in a few words: "The days are long, but the years are short"; "Accept myself, and expect more from myself." Sometimes these are a bit koan-ish: "Happiness doesn't always make me feel happy."
I summed up the present line of argument in this way:
Happy people make people happy -- but you can't make someone happy.
