Sometimes, a topic that I've touched on in one of my log entries may need a little elaboration, or I may want to put thoughts scattered around many entries together in one place. And so I'll periodically contribute short essays to this site.
For example, I might include an essay on a controversial subject, like the effectiveness of capital punishment. Or I might write a personal essay about growing up or about my philosophy of life or child-rearing.
Writing essays requires a little more work than writing log entries, but it also gives me a chance to really shape and express my thoughts.
