"But that's just the trouble with me, I give myself very good advice, but I very seldom follow it."

That explains the trouble that I'm always in.
Be patient is very good advice,
But the waiting makes me curious.
And I'd love the change, should something strange, begin.
Well, I went along my merry way, and I never stopped to reason.
I should have known, there'd be a price to pay, someday, someday.
I give myself, very good advice, but I very seldom follow it.
Will I ever learn, to do the things I should?

- Alice in Wonderland (1951)

I find this to be more and more true with every passing day. I wonder if this is true for most. Is experience teaching you the lessons you'd rather not learn?
