I should not have tried to directly resist feelings, but another thing I did which is good is lightly trying to make a tiny positive feeling become huge, which can do things like shifting focus and indirectly resisting exclusive attention. The only thing I can think of at the moment where I should advise resistance is if you feel negatively about someone being with someone else.

Proper use of control over feelings will be in the Pansystellar Architecture for sure.

Edit: also gotta stay away from lust
