(1) Set yourself some ground rules at the start.
(2) Review the ground rules regularly. Are you keeping them? If not, what should change: the rules or your blogging practice?
(3) Blog regularly, but don't let it dictate your life.
(4) Tell friends you're blogging and encourage them to comment. When they do, you'll get a huge lift.
(5) Add pictures if you can. That will cheer your blog up considerably.
(6) Try to be self-aware but not solipsistic.
(7) Enjoy yourself.
