True, agile is a collection of "very small nuggets of common sense wisdom". But one thing that often gets missed is that common sense is often very hard to implement properly; this is where a good agile trainer will help.
I can think of dozens of changes I should make to my every day life based on common sense (don't get stressed, spend more time with firends and familly, save for the future etc). Why don't I do them? Because it's difficult to align these "simlple" truths with the overall complexity of my environment and competing pressures. There's always complexity in the system, agile just simplifies one part and moves complexity into other areas e.g. having a highly trained and skilled team.
Don't confuse "what you should do", with "how you should do it".
For example the what is "do not get stressed", the how might be to plan your day better, keep your life simple, etc.
These small nuggets usually talk bout the how, but a lot of people either think they know better, or have resigned themselves to the fact that it really is that hard.
