Certainly not a problem unique to INTP, I just said that because your problem seems so familiar - personally and from others that I know.

Please note that this is not about MB, it's about getting hints about who you are and how you use the information you seek.

I was not aware of MB until a friend IRL told me that I might be a certain type. I took the test, and from there my world seemed to open as I at least had a way to learn more about myself.

I read the term "information diet," and I think that is what it comes down to. I've had to do this time to time. Having a motivating side project to help you pick between what is and is not relevant to you at a particular time is a good idea.

Anyway, good luck.
