Wolfish: one is actually supposed to avoid nisyonos, so becoming more social in Shul as per your scenario is the opposite of what we are supposed to do.
I remember learning (way back in school) that one should imagine being in a situation where literal mesiras nefesh is required and further imagine oneself passing the test. Basically we tell Hashem — and ourself by reinforcing our beliefs– that this is how I would act if tested. This can probably be applied to most of the aviros you mention, so play a historic scenario in your mind if it’s not relevant today and pass with flying colors.
I wouldn’t expect the schar to be the same, but definitely enough to say I haven’t done x without feeling hypocritical.
