At my age, I realize that my most precious possession is time, and I've got too much unfinished work to do to spend even a minute talking about myself.
My husband used to take care of the business part of this, and after he died I found I wasn't really any good at it. I hate remembering who owes me what and bugging them if they haven't paid me.
I'm glad I started so young, because you are really able to endure so much at that age.
