Whenever you are unsure about something or have a feeling that something you are going to say or do might be wrong. Ask yourself first if your words or actions are going to be helpful. Think what will be the consequences (long and short term) and who will be effected by this.
Perhaps it would also be good to look at your life in these terms. Ask yourself, has my life been helpful to others and to my own spiritual development?
The answer you get when looking at your behaviors and your life may set you on a better course.
