Word of the month

Shit.

I seem to frequently use that word alot these days. Particularly this month. And it's not getting any better, I'm almost hearing myself swearing every damn day. Why is that?

It's not like I say it out loud, it's only almost like a whisper. But it comes from me regardless. It happens when
a) I forget something important OR
b) I feel uncomfortable with something, whether it's good or bad OR
c) I miss something so obvious I shouldn't be missing it in the first place OR
d) somebody/something distracts me when I'm so busy focusing on something else
