Two comments: When you stated that in certain voodoo situations a lot of profit was made there, you failed to mention that a lot of losses were made there as well. If they weren't, you simply haven't done it enough, because they will surely come.
Second, your mental attitude and emotional state can influence your play and cause you to make errors and inappropriate decisions. I don't think it is possible that they cause losing when you play perfect and make all the right decisions. That would defy logic, at least, based on any known facts.
