Na, you’re set, man. In just a few years your youngest will be grown and out of the house. Your expenses will drop dramatically, and you c an start saving even more to retire early. Travel more if that’s what you want. Buy the things you’ve held off on for the last 20 years. You have another kid now, and you’ll be freaking 60 when they finish high school still working, of course. It will completely change the course of your life. You probably can’t even remember what it’s like to have a baby. We forget those details so fast. It’s hard work.
