I remember this point in high school.... I could NOT WAIT to get the heck outta there. The funniest thing is that I missed it ALOT once it was all said and done. Friends move across the country or farther, and all that fun stuff.
My school had 8 class periods during the day (technically 9, with a 0 hour gym class starting at the crack of dawn.... no thanks), and I went 1-8 all 4 years there, and still managed to barely graduate. I never failed a class either, or got kicked out. My guidance councelor is to blame..... I ended up taking a freshman health class as a Junior (yes, for the first time), and a sophomore consumer management class as a senior. Technically, I was half a credit short in PE classes to meet the graduation requirement. I had to take a proficiency test for the consumer Ed class to try and test out of it, and missed the mark by THREE POINTS!! So, I had to have an approval from the district superintendant & the school board to have an exemption on the 0.5 credit underage on PE classes (seriously, how could they keep you from graduating because you missed half a year of playing outside?). So yeah... I also didn't have a SINGLE study hall during those 4 years. Every class period was an actual class, except lunch, and I suppose Band is debatable (percussionist). Man, I really miss Marching Band.... those were good times. I carried a marching snare my Junior & Senior year.... those drums were sweet.
Anyways, apply yourself, and try to whip yourself into shape, and getting in the routine of putting forth much effort.
I am 24, and I still am not sure what I want to do "when I grow up". I would like to get into something with hardware design for computers, but I don't even know where to begin..... err, well I didn't a few minutes ago. I guess I will look into Electrical/Computer Engineering as UA_Iron suggested. Only thing that stinks is that I have to wait till NEXT MAY to do it, if I can even afford it at that point.... the mortgage on this house is breakin my back here...
