(New York Times) — Small-business owners are often described in monolithic terms. But as I rediscovered during a conversation with three women who run companies, their goals and motivations tend to vary. When I met recently with Jessica Johnson, Susan Parker and Carissa Reiniger of ournewly formed business group, we talked about their long-term goals. (Alexandra Mayzler, the fourth member of the group, couldn’t make the meeting.) I was particularly curious about their thoughts and attitudes about eventually exiting the companies that they or their families — in the cases of Ms. Johnson and Ms. Parker — built. Ms. Johnson said that exiting Johnson Security Bureau would feel like walking out on a spouse: “My daily struggle is, how do I keep the business going successfully for as long as possible, while protecting myself and my interest?” She added that she did not want to turn 75 one day and find that she was still trying to find security guards to cover a client at 2 a.m.
