What you can change is a drop in an immense ocean. And that's ok. Yo can either ignore the rest of the ocean (denial), or make peace with the fact that the tiny drop of the ocean you can control is all that really matters.

That's (again, in my opinion) a really depressing and defeatist way to look at things, and at worst, a poetic way of saying "fuck you I got mine".

Well... it does have the advantage of being true. I'm just explaining one positive method of coping with this vast and amazing universe. Do you have another?

Is it that the glass is half empty or recognition that a glass cannot hold everything the world can pour into it?
