Here is an excerpt from a helpful article in Forbes.com. There are plenty of practical tips that are not about repressing emotions (not good) but managing emotions (necessary). To read the entire article click here.
When you're feeling cranky, it's often easy to pinpoint (or point fingers at) the problem: your boss, your husband, traffic. But while any one or all may be a problem at the moment, they are not in control of your reaction to them. You are.
Managing how you respond to others is oftentimes simply a matter of managing your thoughts, says Steven Alper, LSCW, a consultant with the Scripps Center for Integrative Medicine who teaches stress-reduction techniques to executives.
For example, if your boss gives you an extremely tight deadline for a project, it's easy to get caught in an endless spin cycle of whining: I can't believe she did this to me again! Doesn't she realize I have 10 other things to do this week? Not to mention a family at home that needs me--not that she would know what that's like.
In other words, you're wasting precious time and energy ruminating about the past (all those other 11th-hour assignments) and fretting about the future (not finishing in time to get your kids from daycare).
The solution, instead, is to bring yourself into the present. Either get to work, recruit help or explain to your boss why the deadline is unrealistic.
