I agree with the sentiment of not getting caught up second-guessing yourself, but I think that the line of reasoning you're espousing destroys any hope of learning from past mistakes, and by extension, diminishes the importance of carefully considering future decisions. If I don't look back and learn from my mistakes because I never know what would have happened in the other case, why bother putting any thought into my current decisions? Very shortly they'll be in the past and I can avoid regretting them as well :) I wrote a post about this where I hopefully explain in a little better. Just don't get caught up on the word "regret": http://ryanwaggoner.com/2010/08/why-im-learning-to-love-regret/ http://ryanwaggoner.com/2010/08/why-im-learning-to-love-regr...
