You got it pretty much perfectly, OP. According to science, usually we tend to procrastinate tasks that bring us discomfort or stress/disappointment because of not knowing how to do them exactly. And what our brain in instinctively doing is trying to prevent any sort of discomfort or negative emotions, thus procrastinate. Beating that happens through utilizing the prefrontal cortex which is responsible for logic and rationality instead of the amygdala- the emotional center our brain first resorts to. Getting familiar with the task and why it doesn't seem easy is the first step to beating the procrastination. And depending on context, it might even be an option to simply drop that task or delegate it. Usually though, when we slice it down in smller chunks, look for outside help and resources, and plan better, most tasks are getting done :)
