Thanks, that helps (if it reflects the comments intention).
I still think that under this explanation it should have said "Our time is not worthless" instead of "Only if your time is worthless", which to me opens it up to other possible interpretations.
And: What really is "free time" then? Thinking also takes your time, sitting outside and watching the world also takes time. Whatever free time is, I absolutely believe it is not worthless. :)
