The second part of trusting you hearing is having decent room acoustics in the listening room where you make decisions. This is the most commonly-overlooked aspect of home studios, and it affects everything, so it is worth putting a little effort into. You *CAN* treat a bedroom studio pretty easily and inexpensively, and the difference is anything but subtle.
There is a sticky at the top of this forum where I and others have said quite a bit already, so refer to that for details. (Hint: do NOT stick any acoustical foam or egg crate on the walls until you understand what you're doing).
