Haha true. In fairness, post kids, I had to become very selective about what I do (farewell Netflix and side projects) but the things I really care about, I do perhaps more than pre-kids.
I used to be very selective about going cycling, for example. Too early, too late, might rain, wind a bit gusty. But as a result I often didn't go. Now, if I have a window of opportunity, I just go, even if it's drizzly. And I go overall much more.
When I was deciding whenever to keep the kid or not when my girlfriend got pregnant I realized that all the things I couldn't do with kid I wasn't doing anyway, because I wasn't motivated and focused, and ironically, later when I got a kid I did lots of those things after all. Having someone who depends on you makes you focus on what matters. I mean you can always be a lying ass but if you're even remotely honest and have a bit of shame, starting a family is amazing accountability method.
Still get far less done than many parents posting here. There are upsides to a rigid routine and not being able to put stuff off as easily.
