One "superpower" from being married with kids is that your life becomes a lot more predictable. Like, having sex regularly and spending quality family time is probably a healthy part of a balanced, productive lifestyle, and is a good counterbalance to the stresses of a demanding career - it's nice not to always be thinking about how you're going to get laid, or in the event that you do become successful, whether or not your partner is just gold digging you or something. Although a lot of that depends on who you marry and making sure you're both doing good maintenance.
