Every summer, I make the same mistake. I start to get really optimistic.
I don’t mean in general; I’m not talking about how I feel about humanity or the nature of life. Those things aren’t quite so seasonal. I mean, I get optimistic about what I can realistically take on.
My wife has a reduced work schedule in the summer. My day job doesn’t officially have less hours in summer, but there’s a natural slowdown to projects as people take vacations with their kids. My kids have less commitments. We take days for ourselves. And I’m generally pretty darn productive.
