My life is going Nowhere :-(?

After My H.S.C ..I Wente on pursuing endless courses..most of them which I didnt complete.I also went abroad to get a taste of a life.But now after 4 years..I see my career going no where.My parents freak me out everyday by reminding me that I am a loser..by giving examples of all my frnzz who hv done engineering and stuff and got a great job with a great salary..but as of me..even my course is not completed.And even my parents dont lyk my course which is hospitality studies..they say their nose will be cut if anyone came to know dat even after sending me abroad for studies.I am just a Waiter rather then som engineer..PLS HELP ME OUT GUYS..I am totally clueless of my life as it is going nowhere :-(
