In business (or even in non-profit), it's no longer adequate to understand The Bottom Line, including analyzing the outcomes from resources. The foundation of American capitalism is contract law, especially the protection of private property.
To be heard, to be influential and to reduce the stress in transactions (as well as dealing with social nuisances) we Baby Boomers have to think/act like lawyers. For that, no, we don't have to go to law school.
In my early 40s, I was a 1L at Harvard Law School. There I received an offer to return to ghostwriting. That I did.
Meanwhile over the years I have followed the media's analysis of cases. I have read books and articles on the ins and outs of contract law. On my syndicated site Law And More, I have deconstructed points of law. That has included live-blogging.
Usually, I can manage my own legal matters. For those I need a JD, I know enough to specify exactly what services I want, a la cart. If the lawyer can't accommodate that, I shop elsewhere.
Thinking like a lawyer also prevents us from making dumb interactional moves. If I say this to that professional, goes my thinking, such language can be interpreted as what can be made into a criminal count or a civil charge. In addition, thinking like a lawyer enables me to stop what I perceive as harassment or bullying behavior by those in the social loop. The language I leverage when dealing with them sends the message: Don't mess with her. Professional life is stressful enough without being a victim of public nuisances.
