I don't think technology can ever fix personality flaws, especially not the desire to find an easy way out instead of doing the work yourself. Or, let's put it this way: any such technology that could overcome your nature would destroy your personality as it was, and probably be used by governments to "fix" their population. So let's not.

I wasn't even thinking about technology. I was more asking about a proven methodology based on this principle that gives someone a structured way to do the work themselves with a high likelihood of success. It's one thing to do the work, but it's ideal to know what kind of work is best to do.
