Me: trying to save money for a 3d printer, so I can make my own pen blanks.

My friend: Hey, would you start making this item for your shop?

*proceeds to show me an item that would require I buy a bunch of different chuck jaws I don't have to make properly.*

In time when I have money... I can barely afford to operate my business on the sales I'm doing right now, let alone expand to multiple new projects at the same time.
