I have that common female affliction of having to keep an eye on my weight. Which makes it sound more like an occasional hobby, when in fact it's more obsessive than that. I have to remind myself of what I really want (to be healthy) several times a day, to counter the desire for instant gratification between the foil layers of a chocolate bar. I must be doing something right; having shed more weight than I care to admit, I'm now afraid that any slip will be the first step on the path back to Chubbyville.
Every so often I refresh my tactics for keeping myself in check, and my latest is a rip-off list of six 'targets' for my day. I have a small notebook (it was a freebie with a magazine) and every day I fold the page to leave just a small margin near the ring-binding. Down the larger side, I write my six targets (eat my five fruit and veg, go for a walk, vacuum the lounge, clean the glass, write one report, etc.,) which all have to be manageable, and then I cut a line under each target. Then, as I achieve them during the day, I rip each one off and make a little pile, which I throw out at the end of the day. It keeps my priorities clear in my head, and it helps me to be realistic, too.
Today I gave myself a writing target - that I must write for half an hour. I decided I couldn't really afford the whole hour I'd promised myself at the start of the week...but it was addictive. I ended up tearing myself away from the computer well over an hour later, already craving the next time. My fingers tingled with the joy of having written. Even though I'll have to force myself back to report-writing tomorrow, nothing compares to how right it felt to write today...it was even better than chocolate.
