I've been feeling similar to you, man, with the children and working my hobby. The latter one works different for me, though, since you're at least in a lateral field of your dreams. Me, I hope to do so when I move to Chicago.
As for the kids part, I'm kind of scared by it. The fiancee has pretty much given us a deadline of a couple years since her body won't be able to handle babies with much health after a bit.
I kind of figure, though, that once kids go to school. . .even though money comes into picture, at least I'll have more time to dedicate toward the dream job that had the foundation created by me earlier.
yeah. . .something like that.
I really don't have it that together as I possibly may have made it sound.
