There's one big difference: your professional-needs photography has importance beyond itself. Other than another pro snapper, who can claim that? As a retired pro, that's the single biggest disincentive to getting the camera out of the safe: who's going to care, and if only myseslf, it doesn't much matter because I already know I could do it well over many years. I loved my genre; with that removed, there's not much left to excite, and playing at it with the wrong cast just brings ultimate disappointment.
