I turned 40 this year. That brought a significant shift in how I think about spending time; I'm much more aware that there are a finite number of books I'll read, programs I'll write, stories told to children etc This mindset has been surprisingly freeing because it encourages me to say "No" more often, to the things that if I looked at them objectively feel more like an obligation ("sigh, I should really finish this book before I start a new one") than an opportunity.
