Go for it Dude Changing Jobs/Careers is one of the things your 20's are for , you should set your self a time line though ( Now I'm sounding really old) like 5 years and give it your best shot , then reevaluate where your at and see if you want to carry on or make a change again, Are you Gen Y or Gen I ? I just cant keep up these days, either one isn't supposed to worry too much about long term careers. I've had 3 or 4 distinctly different career paths and I'm Gen X You so don't want to be in a office at your age get out an explore a bit.
