Speaking from personal experience, I fully agree.TomB wrote: Or even if he finds a buyer it may not be someone interested or capable of running the company as it has been run.
When I retired, I sold a precious metal refining business that was exceedingly successful. It was so busy that I worked seven days/week, including holidays, trying to keep on schedule. It took the new owner but a few months to destroy a very nice business. He was intent on redesigning the wheel, which I found to be sufficiently round, and lacked a desire for work. When it collapsed, everyone was at fault (I was included) but he. Strangely, it had made a decent living for me for over ten years, with no issues.
