Achievement Motivation - Dieting and Writing

Back to school!
People are beginning to say that September is the new January with the beginning of the new school year and promises to lose weight or take up more exercise or a new hobby.
I've been trying to lose a few pounds this summer, but I wasn't trying very hard and nothing happened: too many tempting things to eat and drink!
But a month or so ago, I thought I would try harder and cut down at lunchtime, because breakfast and dinner were generally ok. So I got some Ryvita and cottage cheese which I ate with some lettuce, tomato, cucumber and red pepper - delicious and satisfying! I was so pleased to have lost one and then two pounds, that it encouraged me not to be so tempted by biscuits, cake and chocolate and keep it up.

Isn't that like writing? I find it's easy to put it off if I'm not under any pressure to write. There are too many nice distractions like the Internet! But when I do get stuck in and make some progress, it encourages me to keep going. After all, I've come this far and it's beginning to come together.
Good Luck with your writing: I'd better get on with mine!
