Cosmic revelations
I forget. A lot.
I do things and sometimes, for no reason at all, they come and bite me in the ass and I'll stop doing them, only to forget why I stopped doing them after awhile and I begin to do them again only to regret doing them again at all.
This will go on for a few times and hopefully, by the end of the a few excruciating cycles, I will remember that some things/people/matters are just not worth my effort and (already very scarce) time. And that I should only keep trying for things/people/matters that are actually worth my effort and (as mentioned, scarce) time. So there.
