I think it's more about asserting yourself to the degree that you're able to be persuasive, and no more. For example, it's possible for me to be correct, but not be able to persuade others to my point of view. If I take up a lot of group time ineffectively arguing my point, then that's a waste of everyone's time. If I eventually get my way because I'm persistent and won't drop the argument, then that's a short-term win but it comes at the cost of my social capital.
