I would suggest that your expecting-father status and future projection towards children(s) education speaks to a strong willingness to commit. Indeed, it's this existing commitment that seems to drive yr risk-aversion.
So, like most things, there's a balancing act. I've been a serial entrepreneur for almost a decade (we're the same age) and being in the flip position (owning a growing little enterprise but being single) I can't say it's any easier over here.
It seems to me that in a perfect world we can find a synergistic interplay between work, friends, family and whatever passes for "fun" in our lives. It's not easy though, as so many situations and preconceptions are geared towards zero-sum/either-or type decision-making.
Anyway, good luck! Keep plumbing the depths and you're bound to come up with goodness.
