#1.) Dress Up. You probably can't do anything about what you've got on TODAY. But wearing your best outfit makes you more confident. And just looking like you're ready for work tends to make you FEEL more ready for work.
#2.) Do Something Nice for Someone. Or do something nice for the whole office, like bringing donuts to work. Research has shown that one of the best ways to improve your mood is to make someone ELSE happy.
#3.) Prepare for Monday on Friday. If there's something at work that you dread doing on Mondays, get a head start on Friday if you can.
--That way you'll lighten your workload. And you'll be able to relax all weekend, because you'll know you have an easier Monday than usual ahead of you.
#4.) Make a List of Things You're Excited for This Week. It doesn't even have to be work-related. Just write down three things you're looking forward to . . . like your favorite TV show, or having drinks with friends.
