"I think; therefore, I am" said DesCartes.
So, if one thinks a lot, does that make him alot? Not really.
I think a lot. I have a lot of alone time with which to think. I think too much. And I find out I am not much; not much of anything, really.
I think about all I am, all I've accomplished, all I need to accomplish, all I want to accomplish and I find...not much of anything, really.
Solomon said, "vanity, vanity, all is vanity. He was more on the money.
