Horton FAIL, Waxman SMASH: How Sean Waxman Helped Me See the Light
You will never disagree with anyone in this world more than with yourself - your past self. Remember the political ideas you had when you were 21? Remember the people you dated in high school? Remember rat-tails? (I had one.)
Some of your worst decisions weren't a big deal in hindsight. You were younger then, dumb, just getting started. It's to be expected that you weren't going to get it "right" the first time around. Some choices were horrible. You should have known better. You had the chance, and you chose badly. You knew damned well what you were doing was wrong, and you did it anyway. Now you look back with regret and shame. Most of your choices fall somewhere in the middle - not particularly bad, but not completely forgivable either.
