I like to take at least 5 minutes each day to totally let go. I also realize how terrible that sounds. Anyways, let's just continue under the illusion of me possessing a high maturity level...
If I'm feeling stressed, depressed, self-pitying, or if I'm just already chilling and enjoying myself- I try to take a few minutes each day to just stop. Generally I'll put on some super chill reggae, sit up straight, and let go of all the negative energy. Once all my negative energy has been lifted, it can be replaced with positive vibes.
I then usually proceed to have a private dance party in my bedroom and jam out to Shakira or Britney.
I've found that this ritual helps A LOT in calming me down and allowing me to truly live in the moment. Life is only so long, so why spend it stressing out in a situation when the exact same thing would happen if you weren't stressing? Of course, I don't mean to just slack off, but if you've got a big test the next day, then does studying while stressed out help you more than studying with a relaxed and pliable mind?

Do you do anything to calm yourself down and chillax?
