Speaking from personal experience, any time I'm feeling a bit down I call a friend I have not spoken with in a while and just shoot the sh&% with him/her. Both our days dramatically improve and we usually end the conversation with a smile on our faces. This Friday I invite you to reach out to someone you haven't communicated with in some time, whether it be a text, phone call, email, etc. Drop them a line and spread the light and love that lives inside you. You'll end up brightening their day, as well as your own.
