I am starting to make a "Positivity Wall" in my apartment.

What is a "Positivity Wall," you may ask?

It's just as it sounds -- hanging positive quotes and affirmations on your wall.

I got this idea from my friend Caitlin Henry who, shortly after moving into her condo, started searching for positive quotes on Pinterest, such as Theodore Roosevelt's "Do what you can, with what you have, where you are." She framed the quotes and displayed them in her bedroom and in the hallway.

"Having a positivity wall has been a game changer for me. It's always good to think positive especially when you think everything is going wrong in your life," Caitlin told me. "It is easy for me to sit and feel sorry for myself but seeing positive quotes reminds me that there's more to life that one simple event."

For me, the self consciousness only comes when the room is silent and I'm by myself. No one is there to say, "Stop it, you're beautiful! You've got this!"

When I'm coming home after a tough day at work or an exceptionally bad date, that's when I need the reminder, "Better things are coming." The purpose of the "Positivity Wall" is, when you're feeling down and you're by yourself, you can be the one to tell yourself these things.

When you're having a bad day, it's hard to think positive. These quotes on the wall are like letters sent from my happy self to my future not-so-happy self to remind her that it'll be okay.

So, why is it so important to keep your mind thinking positively?

Science writer Susan Reynolds said in Psychology Today, "Happy thoughts and positive thinking, in general, support brain growth, as well as the generation and reinforcement of new synapses, especially in your prefrontal cortex (PFC), which serves as the integration center of all of your brain-mind functions."

For those starting your own positivity wall, here are some ideas from Pinterest and on SkinnyMom.com. Just print out the quotes and frame them. It doesn't have to be an expensive project.
