I started keeping a journal on my first trip west, 2007, and have continued daily since then. I mention things like first snowfall, big storms, unusual temperatures (high or low). What I'm doing each day (laundry, grocery shopping, sitting a grandchild). Bowling scores. Health appointments (for both Seelerman and I). Sometimes I talk about worries (haven't heard from Seelerboy for awhile. Seelergirl sick again). Occasionally cute things the grandchildren say.
I get visitors to the house to sign it - their choice of just a few words or a half page. The same - when I go on a trip I get my host and/or the people I meet to sign. I have Marcus Borg, Greta Vosper, several WonderCafe folks.
Sometimes we refer back to it - when were we last to see your brother in Saint John?
Sometimes it seems a chore. I'll get a few days behind. It's surprising how hard it is to remember something I did just two days ago. But so far I've always been able to get caught up.
No deep thoughts. A friend at Writers' Group will write about nature, philosophical thoughts about life and death, changing seasons, the meaning of growing old, things in the news. Nothing like that for me. The first robin I see in the spring might get a mention - for him its a two page essay.
