I only have two:
1) Waste less food. That means cooking less, eating up leftovers before they go bad and making use of things like the ends of celery.
2) Write one thank-you note every week. Find someone during the week who has touched me in some way and thank them in a hand-written, snail mail note.
OK, one more. I want to add pictures to my blog. We'll see how that goes.
