At one of my networking events, I was talking to someone who described their business as owning a job and not a business or a career.
They were discussing what will be the survival rate of the business, meaning what is the survival rate of industry rivals.
Finally, can it be sold, when you want to retire. If there is nothing to sell, then you really just owned a job.
When I started out, in the very beginning, it could be that I only owned a job, but it grew and I bought a space and hired employees. So just cause you own a job, does not mean it has to stay that way.
