does it really worth ?

Today being one of very agitated day in my life,was just thinking of the future and how it would be without current things.The friends ,daily college routines ,bunks,low marks in sessionals, one night preparations before the exams really just imagining life without things kind of feel depressed and  really feel like doest it really worth growing up ? we all are thinking that life would be good with good marks in exams and then a good job but will these things can really be source of happiness and can it really make life better from what it is now , i personally feel it just cant.
but then what i really need to be happy in future? I tried to satisfy me with various answers but really none of them suceeded.
I personally dont want a life strangled into various aspects of life . I hardly feel happy with those things that a normal person would have in a normal circumstances. I reallly dont think life is worth the way it is for me now ,i might be one of the happpiest person in future but currently the way i am looking towards it i just do not find it joyful and a good one . A great line which i read somewhere "one must know true meaning of life to live it pure. "
