Felt scarcity of opportunity makes bad moods worse

I've noticed my mood follows a sine wave of doom with my predicted dating prospects and that this isn't ideal. One particular way in which it is not ideal is that the sine wave makes my dating prospects worse* when I'm in the negative region of the graph.

(*perhaps practically nil? I dare not say so, because believing it may make it so.)

In particular, sometimes I'm in the negative region when I go out and meet girls. This is, as discussed, not ideal. I'm in a crap mood, so I at best I'll be friendly enough but a little mechanical, and at worst aloof. I'm not going to be fun. I'm not going to be funny. I'm going to have a terrible time practicing any of my skills.

Here's what makes it really ugly: Those opportunities feel scarce, so I feel like I have to make good use of them. Four out of seven days of the week, i.e. a simple majority of my time, I feel like I have essentially nil chance of meeting any lady that day that I might have a shot with. This feeling of scarcity tends to shift my mood toward the negative region of the sine wave. The other three, it's a tossup, but at least the odds are not zero.

What's horrible and crazy about this wrinkle is it's another case of my mood swinging in a counterproductive direction based on my predicted prospects/opportunities. If my opportunities are scarce, I'd like to make the best use of them that I can. Getting moody means crippling my ability to make good use of the opportunities I do get. So getting upset over felt scarcity of opportunities is counterproductive.

I'm illogical and I don't like it. Oops. Fuck! What else is new?
