It's okay to be moody on Monday and Tuesday. Try not to be moody around other people, if you can help it, but don't beat yourself up for your feelings. And besides, by Wednesday, everything will go on the upswing and stay that way. Thursday will be a jovial day, too. Bringing your lunch to work on Friday is a smart idea -- as the week winds to a close, strategies for financial shrewdness figure into your thoughts -- and Saturday, even though you want to go shopping, not doing so is a much better plan. Communication and creativity define Sunday.
