Who's Insecure?

I'm typically very leery of "advice" that takes the form of "here's my advice to you" but I liked this post over at Marginal Revolution. I particularlly liked what one of the commentators had to say:

You think you're exceptionally insecure, at your age. What you don't realise is that everybody else is too, and that this never goes away.

I think that this is true to a much bigger extent than anyone is willing to admit. However, I will say that having children and dealing with the everyday compelxities of their situations has given me the confidence to know that I can deal with almost everything, and that knowledge has been extremely liberating.
