Small successes can make for a good day. It's great if those small success are recognized by our friends or co-workers, or supervisors but that doesn't always happen. Rewarding yourself is always a winning plan.
I have a large yard. It can take hours to mow. I've implemented a system whereby, based on outside temperature and grass length, I get beer tokens that I can cash in for adult beverages.
[Granted, I really enjoy mowing the lawn most days. It gives me a repetitive task that requires little thought itself where I can either think about things or think about nothing. It's two to three hours of good day in any case.]
If you don't have your dream job, if you are just marking time until something better comes along, you probably need something to keep you going more than a paycheck in two weeks. So perhaps a stash of chocolate should be part of your make-today-a-good-day-by-rewarding-myself kit.
You should know where the closest craft store is if that's what makes you happy so you can pop in and get some scrap-booking thing. Or maybe you need to keep a Starbucks or iTunes or Amazon gift card charged and ready for when you deserve a reward.
If exercise or napping is what you love to do reward yourself with time for either when you deserve it . . because you deserve it.
Go ahead. Reward yourself. Make today a good day.
