Sometimes when the going gets rough, the best thing you can do is breathe.
Step outside, get some air, and remind yourself of who you are and where you want to be.
Something as simple as getting fresh air will help to clear your head. That can be hard to do in some places with all the air pollution, like where I live. On a side note, I recently picked up AirPure, an air purifier that doesn’t actually require a filter (saves me money) and it’s made with nano-membrane technology that’s kind to the environment. You can get it from QNET here.
Anyway, if you’re feeling stressed, remember to take a breather.
