I think you are "just warming up!"
I told myself I would only have a "few" inks of a "few" colors & maybe same for pens; that was several hundred of each ago & I just think of myself as "serving my Ink Masters," who have preceded me in the joy of the many nuances available. Once you admit it is "bigger than you," it becomes much easier!
My Mother loved textiles, quilts, coverlets, fabric to make same & always said, "they are easier than the animals living with her; they lie still, MANY can be stored in drawers, cabinets & chests, without feeding or going outside for their "needs." Of the many things I have enjoyed, pens & ink take up so little space in comparison, I do not worry about it.
Just enjoy what you are comfortable with; you can always divest ones that bother you. I have acquired a couple of very good friends by sharing what I no longer care about & they have not used same.
