Yeah ... I basically got the same kind of comments when I left my math major behind and any thoughts of engineering to pursue ... music. But I thought it all out, did a lot of soul searching, and, despite being a really good math student, chose that which I loved the most. The comments I received ... from how I was going to be a burden to society to how could I waste my mind like that ... were meant with good intent, but without all the information at hand. Just those from outside looking in, thinking my decision was the most illogical, mostly from a money and mind perspective. But, everyone else was wrong. You might be, too, even though it seems most illogical to you.
