i had a bad day at work, and instead of just taking a walk or going for a serf i started getting my co workers on the phonen ding. It takes time to build up trusts with your colleagues - you can easily avrode that trust by being difficult. I try to remember if i do have a destructive day, the person it hurts the most is me. And so even if i feel entitled to be angry at some one, or to take my emotion out on some one like that's really just going to reflect more negatively on me.
