We are each and every one of us wired just a wee bit differently from every other one of us. I am convinced the whole thing is in the brain wiring, some of which is genetic and prenatal and some of which is laid down by trails of experience.
I have considered myself extremely fortunate in that I have not been burdened with destructive addictions on my own part in my life. No drugs (actually, have never so much as tried one), no alcohol (not ideology, but personal taste; I have 1 eggnog at Christmas, 1 Mimosa on special occasions, that sort of thing), no tobacco (smoked lightly for 40 years. Gave it up for the last time in 1983.), and not a shopper or spendthrift.
There has always been a huge problem of a very demanding sweet tooth; thus a very slender girl has been overweight since age 35. Never obese, but I am ashamed of my weight which is 30 pounds over the desired.
But books are my comfort, my first necessity, my fire wall of safety, my everything. I mean that quite literally. I would give up all I own, including my books and my health, for my family. I do love them sooooo very much. But I have to tell you the truth, I prefer to see them and catch up with them briefly and then, well, then be left alone with my books. I swear. This is who I am.
