Im 25 and have already started investing for my retirement (mutual funds, roth ira, 401k). However, I do not like my job and i really do not know what exactly I want to do with my career at this point in time.

Maybe when i do find my calling, i will be in a better state to set up a sure footed retirement plan. If I do fall into an occupation that i really like (for instance - photography), i would choose the 55 with $8M+ USD option.
