I don’t think growthful is a word.
I’ve heard that before.
I’ve used it at least for 39 years . . .
It has persistently communicated exactly what I wanted it to communicate.
However, you need feel no compulsion to use it.
I find it wonderfully effective.
BTW, I coin words right and left.
I enjoy language and I enjoy playing with language.
Some people get used to it. Some don’t.
“I don’t think growthful is a word.”
As far as I know the “Doonesbury” creator Gary Tradeu (SP?) coined that word in a strip making fun of Phil Donahue. I never forgot it for some reason. So ‘on point’ perhaps...
