LOL, "Good Enough" seems like a moving average. I typically think of "Good Enough" in reference to parenting and good childhood development. :P Having said that, I think that "Good Enough" is a where I have spent most of my working career. By that, I mean that I have never had the 'best' equipment. I go out and help Steve Kossack with these groups and almost everyone is much better heeled than I am with fancier gear.

I also know I am not the best photographer on the planet (don't get me wrong, I want to be...and I am not saying I am not very good...just not the best). It is something I am developing every day.

The next question is - when is the gear good enough and do you actually need more given your current ability. Here is the blunt truth...and I realize this is not categorical, but a pretty broad generalization. ALMOST NONE OF US EVER have to upgrade a camera that was made in the last 36 months. I know that no one wants to hear that, but it is probably true. 12 megapixels will handle most situations just fine. 21 sounds like a lot more than 12 megapixels and that sounds like a lot more than 9 or 6 or 3. But camera resolution is measured in squares. i.e. to double a 3.14 megapixel camera, you don't need 6.28 megapixels. You need 9.856 megapixels. To double that, you need nearly 100 (yes, that is right) megapixels. 22 or 38 is not so much significantly better - though it is.

Most of my frustration with my 5dii has not been about resolution. If they eventually announce a 5diii that is the same resolution, I am fine with it. What I want is better autofocus, perhaps some better exposure latitude and cleaner high ISO noise (and lower isos as well). The biggest problem is how hamstrung the camera is compared to a 7d or even a 40d in low light. Once that issue is covered, I honestly don't see myself upgrading for a long time...unless stock companies start requiring higher levels of resolution. But wait - I am not currently stocking or re-selling my images...yet.

So, back to the concept of "good enough" - I think that for most folks they have the toys necessary to be good enough. If you want to do pets, it is typically a camera and a few nice lenses. For the landscape guys, you absolutely need a tripod in addition, but that is about it. Everything else is just bells and whistles.
