Not sure I understand negative money ideas?
I listened to a guy called Remi from "I will teach you how to be rich" and he talks about your "Rich Life".
He talks about spending money on what makes you happy and adds to your life.
If its thats 5$ Latte. Go for it.
Or if you really enjoy watching Netflix with your spouse, perfect, go for it.
And the remove stuff that does make you happy, I like this more Fluid approach for everybody :D
