Or before you open your mouth for that matter.
Seriously, just stop and think about what you’re putting out there in the world for everyone to see and/or hear.
Firstly think about it from the perspective of privacy. Is it really something you want to share? Does everyone need to know about the most intimate parts of your relationship with a person, entity, deity, spirit? Are you screwing your own working over posting it online for comment before it’s completed? Are you sharing aspects of yourself that are more powerful kept to yourself or that make you very vulnerable in a place that anyone can see them?
Then think about it in terms of your own mental fortitude. Are you going to be able to gracefully deal with people if they rip into you? Or if they start mocking and making fun of you? Or, hell, if they simply tell you that you are wrong?
If you answer no to any of the second set of questions then don’t fucking post it. The first are far more subjective.
There is power in silence, in choosing to keep what’s yours as yours.
And there are ways of discussing practices that don’t give away what should be kept intimate.
Think about what you say before you say it.
