I’ve now got a small stream of revenue coming in, and if I didn’t know some calculus, I could prove that it is sufficient for all my needs:
I received some money yesterday. It will take me a finite non-zero amount of time to spend it. By the time I have spent it, some more money will have arrived. And by the time I spend that, even more will arrive…
However, since I do know some calculus, that scheme won’t work for me. I guess I’ll just have to be a Zenophobe.
As my friend Richard pointed out, “A man’s got to know his Limits.”
