If I want a quiet month, or even the whole year off, I can also take it whenever I want. The difference is that my profits remain the same as the business no longer needs me.
None of my staff are salaried, they are only paid on results and work for themselves using my resources.
Having help means that you get the benefit of more than one mind working together and that you can work on your business rather than in your business.
It also means that you end up with much more free time, which is something none of us can ever buy more of.
