I hope you are very enthusiastic about your weekly and daily goal setting. Moreover, I hope you realize what an achievement it is, to have a successful day (and week!) where all your goals have been accomplished.
I am not in favor of depriving ourselves from what we want, especially if it makes us happy. Nevertheless, as a motivation, maybe you might want to shift the day you'll buy yourself that new scarf or the new laptop sleeve...Set it for the end of the week, after you've had a successful completion of your goals.
Let me know later how this made you feel!
