This video made me smile (and mostly importantly, think .. and I rarely think so you know its good)! 

They say you regret the things you didn't do more than the things you did do. Can I just say ... they are full of shit! Ignoring the only not done thing I regret (my essays for undergrad), almost every single biggest regret of my life are things I have done. In fact if I had a chance, I'd go back to the past and smack myself silly to prevent myself from doing these stupid things which actually didn't even teach me anything new .. just reinforced the fact that I am right and not doing things and being a lazy bum is better than doing stupid things and turning into a tosser.
