Here is what I have come to believe: that is total horse-crap! For just about anyone in just about any situation, the "I could never do that because..." fallacy is total garbage. It's a lie your brain (and I would argue, the devil) tells you to protect you from the discomfort associated with change. Even if you're not happy with the status quo, change ALWAYS brings unpleasantness of some form, and so our brains work to keep us stuck where we are because it's familiar and comfortable. How many dudes live quiet lives of desperation because there is some dream in their mind that they have convinced themselves could never be a reality?
