Catch 22, try to travel, have fun, experience all that life has to offer while young. The long term career goals could be hurt preventing you from being all that you could be. So to speak. Wait, focus on the career, and something may happen that removes the possibility of travel and such when older. Of course for some it works out, others, not so much. Nothing ventured, nothing gained, and travel can not only open your mind, it can open doors you never knew existed.
