Same here. ...That's my story in a nutshell, in fact. My HS GPA was downright embarrassing (just a tad too much partying), but my SAT scores got me into UCLA.
There are a lot of folks somewhat slower who are very successful because they have will, determination and character and maybe a bit of luck.
No doubt. ...And conversely, a lot of "geniuses" who haven't done a damn thing with their lives.
Unfortunately, our society venerates pure intelligence and youth over character.
but we can live with that one eh Mo?
