I type significantly faster than I can write by hand, so I find that when I type I only think about my words and ideas, while writing by hand causes my mind to drift away. I end up thinking about what I’m doing and judging myself for writing about my thoughts and feelings. Also the extra effort of writing by hand can lead me to judge the effort against what I’m writing, saying to myself “was THIS really worth the effort of writing down?”
So I could never get into journaling. Livejournal got me journaling back in the day, but when I drifted away from it and found myself unwilling to start over somewhere else and not really into the whole blogging thing anymore, I took the habit private. For a while I would type out my feelings in a notepad and close it without saving (as typing it felt more useful than reading it later). Now I journal in a scrivener file.
