I agree with so much of what has already been said - I was discouraged from daytime reading as a child too. Why??? But maybe that just made it more attractive! As my mother grew frail I used to suggest reading during the day, but she still felt it would be a lazy indulgence... a little of which remains with me I think, so I'm inspired now by the experience of others to make the effort to read more by day. It's definitely easier in the better light too!
How much do you spend on yourself?
