If working a "lowly" warehouse job and dabbling in many different subject areas is what makes you happy, that's obviously perfectly fine. But if you believe that dabbling in many different areas will actually somehow in the long run lead to any kind of (work-related) success you're dead wrong in my opinion. You have to focus most of your time on one or maybe two or three areas (after you have become really good at one thing) in order to be able to make any meaningful impact somewhere. Knowing a little of a lot of things is nice to have, but unfortunately has very little use in our society.
