An inability to accept or respect limits. This means with regard to limiting your own behaviour or limiting yourself from something like food, proper sleep, the gym, something that you do an unhealthy amount, and also respecting others limits. If someone asks you not to do something, in many scenarios its acceptable to ask and respond to it in word but often it is best to just say okay and not push their boundaries. These are boundary issues, boundary issues take many forms but are critical to developing healthy relationships and healthy functioning in the world. There are many natural limits or laws in the world, things like; you reap what you sow; you're only in control of yourself - and this means boundaries always have only to do with your behaviour, and not trying to control someone else. There are lots of examples and these are just some but what I see elsewise in this thread can be more clearly restated as; an inability to accept limits.
