For what it's worth, I like the idea of a diary. I always used a journal in my everyday working years. It allows me and anyone else that wants to read it after I am gone, a kind of bio of my life during the working years. I still reflect back on it and when I read some of the stuff that happened while flying, I would say to myself, "I did that?" I always carried it in my flight bag, like so many other pilots still do today. It's amazing some of the stuff that went on and we forget about.
I read on SF a few other folks either keep or kept a journal throughout their life as well. I just find them very interesting, if I know or knew the person. It's just a "journey" through time as the writer sees it through his/her eyes.
Just keep in mind, Debbie, later on, when your life has changed and you take the time to sit down and read through it and being in your situation, it may be painful all over again.
