I actually think we agree on basic thoughts and that you are misinterpreting my message.

My point is that following that many Scrum practitioners come from doing certain practices _everywhere_. Sure, they say you have to modify the practices to fit the situation, but, in fact, iterations don't actually work everywhere. The focus on practices is not sufficient. Practices change when contexts change.

One of the reasons why some people in life seem to get more of what they want than others might be explained by the fact that these "lucky" people have a less limited perception of where the barriers are.

Let's imagine that you're walking along in the local park one sunny day, and you spy a lovely cream donut (mmmmmm, donuts...) on a plate in the middle of the grass. The grass is very well kept, and there are no people walking on it. They all stick to the path. But you don't see any signs telling people to "Keep Off The Grass".
