Next time you are speaking with someone about something that needs to get done - listen to yourself...do you use "handling" as in "I'm handling that!" or "who's handling this?"
If you always describe what you do as handling you are too going to be constantly disappointed.
Entrepreneurs often bemoan the fact that none of their employees handle things like (they would have done so). Duh!
Handling, fixing and removing problems is of course something that has to be done on occasion, but if it is your management style, your organization will act fitfully and never take on its own responsibility for what happens.
Try to create and sustain processes and an environment where the employees can individually take on what happens as their own. That is managing.
Stop handling; start managing.
