What does "Freedom of my Time" mean to you?

[David Hays]

I read BP for several hours every day (broken up in pieces, but smartphones are a beautiful, terrible thing), and I regularly see people listing "freedom of my time" as one of their big motivations when it comes to RE investing. Now, as a solely-1099 earner since 2012 I understand this motivation entirely, and from some of you it totally makes sense, but I also see this statement from those that are still in their 9-5 W2 jobs. For those that have accomplished some of their greater goals in REI, how do you really quantify "freedom of time", and how does that fit into remaining in a W2 position reporting to someone else?
