4-Operating System to Achieve Time Freedom

We talk about the "operating system" for time freedom, and compare that to the "Apps".  In the pursuit of time freedom, most people get attracted by an "app" (a real estate tactic; a stock market method; an affiliate marketing program; etc).  However, if they've not built the underlying operating system first, then they won't be able to tell whether a particular "app" could be useful, let alone determine if it is even appropriate for their operating system.
