If we want to 'get' difference results, we need to change what we see and then what we do based upon what we see.
The other part is Principles vs. Values:
Principles are laws of nature. Doing 'A' gets you 'B' (ie hard work helps you obtain what you desire) (or quitting smoking makes you live longer -- i supposed one could argue that not smoking makes living worse though so you can't say it make you live better)
Values are chosen. Inflicting these upon others seems to be where the clash comes in. (ie mothers should stay home with children)
