I'm 41, married with three kids. I own a house and a business and by other people's standards I'm pretty successful (by my own I see a lot of room for improvement). On the inside I feel 18. My body is starting to figure out it's over 40. I do think I'm just pretending to be an adult. I often feel like I don't know what I'm doing, but I've started to notice that a lot of 20 year olds seem like children to me and they clearly have less of a clue about how to survive than I do. The aphorism "Old age and treachery will always overcome youth and beauty" is, apparently, true. So I know I'll manage, if only because I've been doing it long enough to have some ideas about how to do it with some skill. Now get off my lawn.
