Frugality in Promotion of Renewable Energy Books

A friend noticed that I haven’t been on as many radio and TV shows as I was a few years ago and I admitted that I’ve been a bit more frugal with use of PR firms to promote my books lately.  When she questioned my choice of language, I explained that I’ve always liked the word, insofar as it’s so different from “cheap.” “Frugal” means avoiding spending lavishly on oneself; “cheap” means avoiding spending on others.  We should all aspire to be frugal, but not cheap.
