I formally started keeping journals in 1981, but had actually kept smaller versions earlier to chronicle things like our move across the country from Rochester to Seattle in 1977.
I am not sure whether to call these journals or diaries. In reading back through them, I see how useful they were for me to solve problems, especially at crucial times in the evolution of my first company, Delphi Computers.
I do wish that I had included last names on everyone I wrote about, and that (at times) my handwriting had been more intelligible. I see from looking back this far that there are patterns I identified that become clearer now. The reading and organizing of the journals will provoke some additional changes in my life as I move forward.
