I've never read that book -- no reason; just mostly prefer fiction, and never got around to it.

The funny thing is that I make a habit of doing what Carnegie describes here, and for the same reasons.

As I've gotten older -- I'm 56 -- I also realize I look like the archetypal middle-aged straight white dude, and my cohort doesn't have a GREAT reputation across the board, so I feel like I should be even MORE careful about the energy I put out into the world. And nothing lifts _my_ mood better than being nice to somebody else.
