I can't remember ever wanting to be anything other than a lead singer in a rock and roll band. Fortunately I got to do it, with some small degree of success... enough to realize that it was far less appealing than I'd always imagined. I was then able to shift my focus just in time :-) But I never went though that "astronaut, fireman, racecar driver" thing as a child.... it was always "Rock Star" :-)
