i wish i could see into MY future...

so when do you know when what you want in and for your life is what you should and will have in your life? i'm in this state of transition, right? as i put it...floating in limbo...and i have waaay too much time on my hands to sit and think. i'm constantly thinking about what i want to do for my future career and what would be cool to pursue. do i want to attempt to be a writer...a journalist? a novelist? a screenwriter?? can i somehow save enough money to pick up photography as a hobby and later try to make that into my lifelong artistic career? could i really become a celeb-photog? an annie liebovitz?? or even an anne geddes? should i continue this novel and uneventful path toward marketing? could i make my mark in consumer marketing? would i be good at it? am i supposed to work in this field? why am i even interested in pursuing this field? how will i know what i am supposed to do with my life? how did picasso know he was supposed to be an art icon? how did lincoln know he would be one of the greatest civil liberties legends to roam this land? how did oprah know she was going to become the biggest household name and one of the richest women? when do my fantasies, goals, dreams, wants meet reality and my fate? do they meet? do they part ways? when do they part? will life always be filled with short fantasies followed by depression rooted in the thoughts that reality is not fantasy?
