Notice the OP mentioned the "feeling" of being able to do anything. It wasn't said in a matter-of-fact kind of way. Windows and Linux each satisfy innumerable use cases.

Good for you! I've been using Ubuntu again for a few months now and it has satisfied my every need, so far!

Profile rank being misrepresentative of my qualities as an individual is exactly what I was getting at. Regardless, I appreciate your thoughts.

I don't know whether this could be attributed to some reverse placebo effect, but now that I drink less coffee, I feel more productive. Whereas before, if I drank even two cups in one sitting, I'd be sure to go into psychosis.

Perhaps that's just me.
