I've read a quote before that states "One man's freedom ends where another one begins" I consider it as a perfect explanation of exercising your "freedom of will - whatever". You are free to do anything that you want but it should not affect anyone around you or else you'll have a problem.

It's easy to say that you are just exercising your "will power" but if it's going to affect anyone (specially if it's not for good) then you should control or avoid doing it.
