What do you do when you feel frustrated?
I will mediate. All thanks to yoga.
When I get upset at work, I will "nam" (complain) all day long. Complaining to my colleague and friend. I think that's women. But I will get over after I knock after from work. That's something good about me I don't bring my work home and tomorrow everything will be erased.
Try deep breathing in and out and keep yourself out from meetings, phone calls, visitors and most importantly your BOSS.
