Your post is written with a positive atmosphere, but I can't help feeling like you've lost something you once found rewarding. And... while it's tempting to think about your own life in terms of opportunity cost, I would caution that it risks giving rise to constant discontent if you focus too much on that. Bertrand Russell has a good quote in "In Praise of Ideleness":
> There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake.
