at the ripe old age of 19

at the ripe old age of 19, or at least in my life, you have to make a decision. You are fresh out of highschool. you maybe have a semester or two under your belt. you feel somewhat on top of the world. and then slowly and then suddenly a realization starts to surface in the part of the brain that nearly always occupies your attention and you wish that it wouldnt. this realization is that you dont know very much at all. the world you know starts to fade and crumble. and all you have left is who you are(if you even know yet), and a set of paths that could lead you anywhere. for me its a mission in brazil. and this scares the daylights out of me.
