This indeed. When you live in a friendly environment, whenever you do something right, you achieve some small success. When you live in an unfriendly environment, you need to get many things right at the same time, otherwise it all falls apart. So if you don't trust yourself to do everything flawlessly, there is almost no point in trying. Also, if you succeed once in the friendly environment, you get praise and more support in your efforts. If you succeed in the unfriendly environment, people assume that you either cheated or simply got lucky but it won't happen again. So even after you succeeded at some small thing, it may still feel like there is no point.
