Takeing care of one self is important to be happy and also perform optimally in the work situation.

The first steps to getting healthier and happier:

1. Eat healthier, try to eat some fruit during the day.
2. Exercise, or if going to the gym is too much of a hassle, skip the elevator and use the stairs or try to walk at least 30 minutes after work.
3. Get your own mug, possible with something inspiring or funny printed on it. Use it whenever you have something to drink. Anything tastes better out of porcelain, plastic cups taste … plastic.
4. Try not to get too emotionally involved with anybody working around you, aggravate yourself over your boss, or the moron in the next cubicle.
