That's me, too.

Teacher's pet, best student when I like something. Then I get bored of it or see it as pointless and give it up. Didn't graduate high school, but went to college early. Didn't graduate college, but lie about it. "Brightest student ever" at one career I was pursuing, but gave that up when I got married and had kids. Took on a leadership project that was ridiculously challenging and succeeded then left. Had one year in the performing arts writing a good full-length screen play, acting in several short films, doing a commercial, singing with a rock band (family didn't know I could sing!) then got bored of that and quit. Started another career, just play at it, but took on leadership. Also, probably going to quit that now.
