I understand your point completely. College should be used to pursue a goal. Otherwise it is a waste of time and money. It worked out great for me but I know many people that became successful without college, and probably wouldn't have been successful if they went to college.
I've always thought that it really stinks that 17-18 year old kids have to make decisions that could/will shape the rest of their lives. We're too young at that age to know what we want to do.
And, yes, I enjoyed math and physics and science all my life. It's okay, I'll wait until you stop laughing...............
