Yes, I believe I use to always feel like that.
Like I was just slowly wandering onward while I watched people walk, run, or fly by.

I've always been jealous of those passionately knowing what exactly it is they want to do.
Even if they change their passions from time to time, at least they're passionate about something.

I'm okay with just trudging on, as long as I am moving along somehow and not sinking into an abyss of nothingness as time continues to rot me.
