Wait until kids are in the picture. You bitch about routine now. Every waking moment of your life is scripted by some unseen hand. You can't do anything spontaneously. You need that routine to get through your day. You can't just take off for vacation at the drop off a hat. you have to take into account the side effects of every decision prior to making it. And let's not even talk about cost. Everyone knows children aren't cheap.
So enjoy these days because they are soon over and can not be had again.
