I do not keep a Journal but I keep lists of all sorts. It started with To Buy Lists for train shows. Then Lists of things bought as to item, date, and price as I acquired more stuff, I wound up double buying. I have lists of items to be done on the layout and things done on the layout with dates. I also have lists of items bought at garage and thrifts, and picked from the trash with item, price, description, and date. I have separate lists for tools, audio, electronics, sports gear, golf clubs and camera gear.
All these lists started as lists on paper and in pencil but I now use simple MS word lists on the computer.
All of these lists have helped me keep up with what I have acquired and have.
I do not have a journal but have detailed how I designed, build and improved my 44 year old layout on a 8 page, OGR forum topic and share it at the OGR link below. Having the items bought, built, modified and dates made this topic possible.

An important journal I am working on is like a family history experience list I keep. It started about the four years we lived in Kingston, Jamaica and the wild things going on in that country at the time, 1976 to 1979. The countries democracy was under siege by communist Cubans but they had a free press and resisted a take over. Recent I have started notes on my childhood during the late 1940s and how we lived to save these memories for my self, grown children and grand children. Being seasoned I find it easier to remember things from 60-70 years ago than last several years !
