Good point regarding value. What I feel mixes this concept up is the calculation of how much is my time worth. Do I take my current net value and divide by my age in hours? Do I take my annual income and use hours in a year? Do I take annual income and divide by hours worked? Do I adjust all results for cost of living? Those are just a few ways you could look at it and each will come up with vastly different results. The value I was trying to establish is simply a breakdown of cost per time spent in something that's intended to be a chosen method of entertainment. Let's say I buy a hardcover book for a newly released novel I've been awaiting, somewhere in the $19.99 range. I read a couple hours a night and finish the book in 5 nights. That's about $1.99 per hour of entertainment. Another key concept for me is that this time spent is a choice I make to do something I enjoy. It's not my job, no one is forcing me to do it and I don't feel any way obligated to do it. I choose to do it because I enjoy it. When I am engaged in an activity I don't enjoy, during my free time, I stop and choose to do something else.
