Future's Endless Possibilities

Well, I deffinitely got a lot of insight on my last post since I posted it. But now it has me wondering. Ok, so everything is possible, there's just certain aspects, yada yada yada, I get it. But how do you focus on just one? Like everyone else, I do have a dream; I have things I want to do, and I have goals that I want to accomplish. But now my question is: what happens in something steps in that could potentially be better than what I've been planning on and working towards? What if I get into the college I want to, work my butt off, graduate and start a great career, but then something happens that could produce an outcome I've never dreamed of and I want to pursue that? What if, in order to do this thing, I have to leave my career and all the other things I've worked for behind? Was all that money and experience for nothing, and realize that I really shouldn't have done all that in the first place? What if I get an even bigger dream that outweighs the first one, now that I've accomplished the first one? I don't know, lots of questioning going on lately. Have a good thanksgiving guys!
