I understand that and in a lot of cases it may be accurate. The article makes a blanket statement "Self-sabotaging behavior results from the same cause..."
I disagree. To me sabotage is a deliberate act intended to cause harm or damage. In my own experience self-sabotaging was just that. I did it deliberately or unconsciously (I was told) to harm or punish myself.
You obviously want to discuss the interpretation of the author and how it relates to you so I'll drop out of the discussion. I will say that this is the third article posted from Psychology Today that is...lets just say, does not appear scientific or even well thought out IMHO.
Maybe it should be retitled Pop Psychology Today
Anyway I think it's great that you find it helpful and I hope others will too
