Summarize this article:

Studies have shown that our emotions are reinforced and perhaps even driven by our facial expressions: smiling can make you feel happy; frowning can make you feel sad.  If you're feeling down, try smiling for at least 30 seconds to see if it helps boost your mood a little. You might even try smiling in the mirror and making silly faces — you might even get yourself laughing. Redecorating can help you feel as though you're making a fresh start. You can do this even if you don't have any money, simply by rearranging your room, or giving it a thorough clean and getting rid of things you no longer need.  Cover your walls with things that inspire you — for example, pictures of places you'd like to visit, or people who inspire you or make you feel happy. Find your favourite photo of you and someone (or some people) you love. If it's not already printed out, print it and frame it, and put it in a prominent place in your home. Take some alone time once in a  while and treat yourself.  Buy yourself that book you've been wanting to read. Take a few hours to sit in a comfy chair and read it while sipping your favourite tea. Have a bath in epsom salts and put on a nice moisturizer on afterward. Have a spa day. If you feel uncomfortable in your body, you'll likely have trouble enjoying yourself. Try doing daily exercises like looking in the mirror and naming 5 things you love about yourself — not 5 things you hate.  If you can't name 5, name as many as you can. Each day try to increase the number until you can list 10 or 20 things about yourself that you like. Almost no one will love everything about themselves; just try to like as much as you can. You are beautiful in your own unique way. The popular saying, “to give is better than to receive,” is true for many people. Studies have shown that the same parts in our brain light up when giving gifts as when receiving them. Examples of good deeds:  Try volunteering for a cause you believe in, even if it's only for a few hours a month. Help a friend, relative, colleague, or neighbor with something you know they could use help with — for example, mowing the lawn, organizing their files, driving to the grocery store, packing up to move. Sometimes you need to get out of your head. Clean your house, doodle until you've filled a page, dance around to your favourite song, or sing at the top of your lungs to it. Allow yourself a few moments of distracted enjoyment as often as you can — no matter how bad you feel or how much you feel you may not deserve it.

Summary:
Smile. Redecorate. Pamper yourself. Love the skin you're in. Do a good deed. Distract yourself.
