I agree that "Indigo" is over-used and often an excuse for other problems that aren't being addressed (like poor nutrition). That said, I do think that there's something going on... whether or not "Indigos" are here on some mission, I don't know. What I do know is that I am an adult (29 actually) who fits pretty much all of the "Indigo" characteristics and personally, I can't stand it here on earth. When you spend your whole life believing you've got some important mission and you grow up and feel frustrated and alienated, wishing you could take back your contract in the first place, I don't think it's such a great thing to be "Indigo".
