ForrestN is not (as I interpret) saying that nothing matters. Just that evaluating the "matter-ness" of something based on some objective like making a difference to humanity is baseless. If staying passive makes you happy, then take that route. If proving mathematical theorems makes you happy, then take that route.

You seem to be saying that the pursuit of a goal in of itself matters, something that is not really at odds with what ForrestN implies, which is that the end product (the result of accomplishing a goal) doesn't really matter, given that all paths end at the same destination.

I especially take issue with your last sentence, which feels like a cop-out. "You may as well move" is a poor reason to move. "You may as well stay put" has just as much validity.
