Another turning point

Here i am again. Tomorrow will be my first working day for my 6th job throughout my career. How long can one hop from one job to another? I just don't know why some people think that moving on is a bad thing. If I were to stay at my first job until now, i think my salary will be at 3k+. This is me, whenever new opportunities are given, i'll grab them, of course only after consideration. It's time to put effort and to cope with new environment again. Let's hope there's a job which i found it worth staying :)
