If you don't know how to set personal boundaries how on EARTH will you ever succeed at running a business? How will you ever climb the corporate latter if you are unsure how to set boundaries? How will you be a good father if you don't know how to set boundaries?
Personal boundaries are a very important part of the foundation to *any* healthy R... be it a friendship, parent/child, marriage or professional situation.
Why do you think corporations spend the time and money they do educating their employees about sexual harassment? Because sexually harassing people in the workplace is an unacceptable BOUNDARY to cross and some people need to be told in a very clear way what is and what is not acceptable.
Don't you want to be the kind of man that knows how to set boundaries that are healthy for all parts of your life? If you are unable to set boundaries why *would* a company take a gamble on YOU and pay you the big bucks? Why would anybody want to go in to business with you or hire your business if you don't know how to set boundaries? What happens when you complete a job as a self employed person and the client doesn't pay you? Will you just be "nice" and hope your kindness helps them realize they must pay you? I doubt it.
