There is no voluntary system which can't be sabotaged by your own feelings. Performance anxiety, overthinking, fear of success, etc. And if you let things pile up without processing them, that becomes another snowballing reason to avoid the system. One's thoughts and feelings ABOUT the system seem to have no way to be processed BY the system, so one just avoids all of it. There is also sometimes an expectation that a system will do the hard work for you, instead of just telling you what you should be putting hard work into in a certain time slice.

I am not betting my life that there is no one who is psychologically incapable of working with certain systems without intractable distress. But I doubt it.
