Almost every time when I was unhappy, down, stressed. I used my own Pick Me Up method.
My trusty method is take a deep deep breathe, hold a while, and let out a big big.
repeat if I have to, and quickly do my stuff when I felt a bit better.
but lately, this method is getting less and less affective.
Do not use this method when you have garlic breath and there was someone in front of you
