The more I studied Jung, the more I realized how one-sided and flawed each type was --- they're all caricatures you shouldn't want to identify with.

The more I studied the MBTI, the more I realized how superficial and "everyone gets to be a winner", corporate America style all the types were.

The more I studied MBTI fora, the more I realized how similar even supposedly entirely different types apparently are, because there's really not much of a difference between /r/isfj and /r/entp, for example.

If you recognize things about yourself you dislike and want to change, write them down. Don't view them through the lens of a superficial psychometric tool and its questionable community and instead focus on finding concrete solutions to the problems you've spotted.
