Now I think what he said just makes good sense, and change is always possible. Time and effort (even unintentional ones) will work on you, and if you don't like where things are at it will take time and effort to reverse. Maybe I've learned patience in the past decade, or it's just a part of getting older - the realization that things are worth working for even if the ultimate goal is nowhere in sight.
So I look at what I've become in 38 years and mostly I like me, a lot. I see where time has paid off, and a few places where time has worn ruts that I would really rather get out of. And that's okay. I've got years left ahead of me to change direction, try new things, wear in new ruts I'm more comfortable with. 38 years down, who knows how many left to go.
