I kind of get this, although it's a bit different for me. I come from a family of talented black sheep.
They are all pretty broken fkt up individuals.
But all are talented artists, musicians photographers illustrators.
Then there's me, Jack of all trades, master of none.

Not so much the white sheep, as the slightly grey sheep of the family.
To be raised in a family where every one is gifted and are leaning on you telling you how lucky you are not be weighed down a complex creativity. How fortunate I am to see clearly without all the heightened emotional distortion that they are inflicted with. ( eye roll).
To be fair my brother is the only one who doesn't behave like this despite his exceptional talents. But then he is more fkt up than most.

I think I gave up trying to discover my niche, and just decided to get on with things as best I could.
I still feel like I am missing something, I keep hoping that one day something will magically click and I will discover my gift....whatever the he'll that is.
