You're probably getting upvoted because there's a kernel of truth in it. Many of the very intelligent people I know have followed this line of thought at one point or another. I have as well, multiple times.

It keeps coming back to "what's the point of what I'm doing?" and I've personally yet to find any sort of answer that speaks to any sort of higher truth than "I'm here, now what?"

A good read, though I think Solomon's version is more evocative.

I upvoted it because, as another commenter said, I have had much the same thoughts before. Some weeks/months I'll have these thoughts everyday.

So basically, I upvoted because I identify with what you wrote.
