Dunno wat to do in the maritime industry

My love for the ships and the sea is forever...but i dont know what jobs should i do in the maritime industry...The job scope is too wide for me to choose....They include freight forwarding executive,marine operations executive,shipping executive etc...This 3 is what i am interested in but dunno which one i like most..So fustrating...I need to know which job i want to do before i can really put my heart and soul in the studies. My fav.module is CARGO HANDLING...the teacher is cute and fun..the lesson is interesting....Okay...that is all
