What is your personal definition of "Productivity" and what do you think is its end goal?

Productivity is a measure of how much you can get done in a block of time. It doesn't have anything to do with end goals.

It's a bit of a silly question like asking what fuel mileage has to do with where you drive to.

I think productivity is a sham caused by what Max Weber calls the Protestant Ethic. But we’ve all internalized it to the point that we feel bad if we aren’t doing it

I measure my productivity in how much art I create and how good a vibe I cultivate.

I suppose I could condense that into "how much beauty I bring to the world".

Productivity is when you do the stuff you need to do. If you can do even more in advance, you are more productive.

Productivity is how fast I'm moving towards my goal. Its end goal is to reach my goal.

Literally it means producing stuff, I guess, so creating physical objects, art, code, etc. It's not something I'd ever really measured or cared about. Many of the things I need to do are not productive, eg revising for tests, but are still useful for me to do.
