Even if we behave according to our wanted path, it doesn't mean we are able to do all the things necessary, at the level necessary, in order to achieve it.

This is a great point. This happens frequently in careers. You get promoted to the position you wanted but it turns out you don't have the necessary skills to excel in the new role. The "what got you here won't get you there" kind of thing. I've seen it happen with others, and it happened to me at least once.
