It's more than just being driven because there are a lot of driven people ( such as myself) that are not w*rkaholics. Studies show many workaholics are also driven to get something done, even if there's nothing worthwhile to be done, or to expand a problem ( make mountains out of molehills) just to feel busy and have a sense of accomplishment. And most of all to be driven to please a someone higher in the vertical matrix.
Those driven with a sense of balance will efficiently solve problems at work for pay, then leave in time for early dinner at home, driven to solve problems and fix things at home and spend quality time with spouse and kids and stay driven to maintain an exercise routine as well as read, relax or keep up with hobbies before getting plenty of rest.
