One way I've used my version of socionics to help me is that I've much less self-critical about certain weaknesses, and also that I try to use my strengths to compensate to be effective. I.e. there's more than one way to be good at... most things.

One thing that I thought was really irresponsible was that my friend's mom told her she shouldn't chase her artistic dreams b/c of her type. Everyone brings something unique and different.
