accept or reject?

haizzz..
these few days i have been being confused by this thing..

i've got an offer to work at a big company.
yeah..it is a good prospect indeed.
but this task is totally new for me..
but i'm still confusing with this..
i dunno whether to accept or reject it..

my fren said that if i'm having difficult to make a decision, maybe just reject it. bcoz i'm not happy. he said if he was me, he will choose the job that he could enjoy, salary that boleh tahan and happy with the job and pressures.
well, maybe he's right..

let me think bout this clearly later..
haizzzzz...
