I hopped from computer engineering, to electrical engineering, to get a bachelors in Art. I worked cross discipline between Art and CS, to publish academically. I got my masters in CS. I was accepted as a PhD student in CS, but at that point, I was so isolated that I essentially collapsed from stress, overvaluing my work, and undervaluing my health.
I work as a software developer now, in the interim of 'not really knowing what to do with my life', being that I've seen so many facets of where I can go, what I can do, and once again, haven't got the faintest clue aside from a small amount of intuition to guide me in what to do. That, and an obsession with everything related to technology, and enough technical/logical/mathematical books to build a house with.
I don't know so much if it's that my surroundings changed that tempered my feelings, introspections, and feelings of isolation, or the experiences I've been through. I'd say it's easy, but it isn't. I'd say it's hard, but it isn't. I just sort of imagine everyone in life goes through something similar once in a while, even if on the surface, it looks totally different.
