Here's one way of normalizing it: what hours can you unambiguously ethically charge to a client/employer as "work?" If you work for yourself or your own business, assume you are doing a custom project for a client. If you work a 9-5 job, obviously everyone throws in some non-work into their day, but don't count these because it's still ambiguous if it's "ethical" to charge these (there are plenty of bosses who wouldn't consider the gym or surfing the net as work, but every boss would consider programming or reading up on a relevant programming issue work.)
