You can call this curmudgeonly, but I've reached an age of my life where I look around at my peer group, and I see a clear line between people who have made wise choices, and those who have not.
I see myself as a peerson who started very much in the poor camp, and has tried in his adult life to make it over to the wiser camp, with varying degrees of success.
I see my job as trying to make sure that the next batch of young adults that come up never have to see what I see, or make the journey I've had to make. My job is to try to get them started in the wise camp.
If some of those in my peer group manage to learn something from this as well, so much the better. I'm still hiking this road as well.
