Just a couple at the top of my head; I'll hopefully have more as time goes by - let's see how long before we realise I may have trouble keeping to them:
1. Donate blood! I've always been meaning to, but the fear of needles, and the face of procrastination just get to me each and every time.
2. Bake a new, never-tried recipe, when each of my sisters celebrates her birthday. I am usually in the habit of baking the same stuff over and over again, because I'm usually baking for one thing or another and can't afford to make mistakes or spend a bit more time trialling a new recipe.
Happy birthday to me!
