Day Eight: Do something creative. Write something or paint something or glitter something or build something. Make something for no one other than yourself.
Day Nine: Treat your free time like a vacation. When you're on vacation, do you check your work emails? Or waste time watching a TV show you don't even like? (Okay, maybe you do, but you shouldn't) If you have any free time today, treat it like you would treat a vacation and do things you want to do. Rest. Relax. Go get ice cream. Read a book.
Day Ten: Clean up the room you sleep in. Cleaning might not conjure up feelings of happiness for everyone, but waking up in a clean room just starts the day out on a good note.
Day Eleven: Try yoga. Don't knock it 'til you try it. I've had my fair share of rolling my eyes at yoga, but lately I've realized how beneficial it is. There's plenty of variety...you can get your workout on and work your muscles, or you can stretch and relax. Both are helpful.
Day Twelve: Make a list of things you're looking forward to. Pumpkin spice lattes! Your anniversary! Vacation! Going shopping the next time you get paid! Christmas! Put the list somewhere you can see it. See? There's so much to be happy about.
Day Thirteen: Do something kind for someone else. Buy your coworker a cup of coffee. Hold the door for someone. Be a pizza bandit and send pizza to your friend's house. Once again, making someone else happy does wonders for your own happiness.
Day Fourteen: Write down five unexpected things that made you happy this week. Make yourself think about it until you can come up with five things. Lots of green lights on your way to work, or an email coupon to your favorite store, or a pretty sunset. Nothing is too small!
