My friend Aaron passed along an article from the Harvard Business Review's site titled Embrace Work-Life Imbalance. This short post is worth a read when considering the topic of work... especially hard work.
It seems to Me that the term workaholic is often less than helpful. Hard work is not a disease.
While there are certainly excesses when family and health is set aside for work pursuits... but in most cases hard work is a great thing... not something to be characterized as a disease.
Take a minute and read the article; let me know what you think.
