I've read plenty of articles and essays that discuss earnest and effective ways to help shake yourself out of an existential funk, but what about simple, materialistic solutions?
Stuff You Can Buy to Make Yourself Feel Better When You're Feeling Depressed and Don't Understand What Your Life Purpose Is and Have the Urge to Maybe Go to Cooking School Even Though You're Not That Into Cooking But You Can't Think of Anything Better To Do.
New Hair
When I put a hot pink streak in my hair last summer, I swear it made me feel sassy and brave and rebellious, which was a huge departure from my normally blond, bouncy hair that mostly made me feel like a chirpy newscaster. If you're in a funk, try getting bangs, or a pixie cut, or highlights, or extensions, or a perm, or new layers, or a new color, or if you're feeling really intense, all of the above. You have nothing to lose! Except your hair. And your good looks. And your self-esteem. Just go to a good hair stylist, OK?
Seriously though, sometimes a little change in your life can spark a bigger one. And your hair is a really fun place to start.
