Sorry for being late with my answer.
SASS is PJs terminology, it stands for Significance, Affiliation, Stability, and Stimulation. The exact categories aren’t that critical, the important idea is that they represent the terminal values all humans seem to have hard wired into them so to speak.
So what I meant is that it’s important to know why you’re motivated into doing action X. If it is because you’ve learned that you’ll gain SASS by doing X then everything is fine. That’s operating under what PJ calls “positive motivation” and you’ll feel as if you really want to do it and you can pursue X without feeling stressed out, by naturally selecting the best course of action, among other things.
If you’re operating under a SASS threat on the other hand, which you do if you’ve learned that you’ll lose SASS if you don’t do X, then your mental state will be completely different. This is what he calls “negative motivation” and there you’ll feel like you should and ought to do X without really feeling like you genuinely want to. It’s usually accompanied by only doing as much of X as necessary to remove the immediate feeling of threat and then mostly feeling bad about not doing more even though you feel like you “could”, “should”, “ought” and similar feelings.
I guess that our situation isn’t that uncommon unfortunately. I hope you’ll also be able to improve your mind state similar to what I’ve done. I recommend reading PJ Ebys comments here on Less Wrong since he’s mentioned a large amount of his important ideas in them. You can also PM me if you’d like.
