What's stopping me ?

A few years back I was contemplating to take up a course I was long resisting. I got a distinction between a conversation; 'Why are you not doing the course?' and 'What's stopping you from taking up the course?'

The latter is actually a very powerful way of inquiry. It does not put a person in a spot.When you ask someone 'what is stopping you?' the context of the conversation changes altogether. It's an empowering inquiry that the person does not resit.
