I've read about triggers in regard to addiction, where the idea is opposite of this -- that an addict needs to avoid the triggers that send him/her on automatic pilot to do that habit over and over. It seems much easier to figure out triggers that result in a person getting drunk (driving by a favorite bar on the way home from work) than figuring out triggers that send a person on automatic pilot to clean out the garage
The whole trigger thing had one big flaw as far as I could see, because some triggers that send people into detrimental behavior are too pervasive to avoid -- for instance, "nighttime."
But I don't know a methodology of how this would work in regard to positive behavior that we are procrastinating on or fearful of.
