There are different kinds of talk:
For example, you are going to need to talk to your spouse much differently than you talk to others, because lets face it, you won't get very far with this way of life without them. Believe me, I know.
For others, they need to be ready to hear your spiel, the whole thing, unless you are just having some kind of water cooler talk.
I liken it to diet. I have been doing the paleo thing for 10 months, I have lost 30 lbs, under 10% body fat, I am 46 and can do things I couldn't do in my 20s. The list of goodness goes on and on.
Lots of my friends/associates ask me what I did. I tell them its the easiest thing in the world and costs nothing. Yet, when they find out that they can't eat pasta, bread, junk food, sodas, etc. they are immediately put off-ie not ready, despite the results standing right there in front of them.
I consider going full "stach" much more difficult than going paleo (also the body of proof is not standing there in front of them either), so therein the difficulty lies. Also, something like diet is completely within your immediate control-no debt to dig out of, no arrangements to cancel, no contracts to void, no new purchases to consider, and no one else to involve.
Now, I am very new to the "stach" so it will be awhile before I am handing out any technical advice on this matter, but they gotta be ready, otherwise you are just wasting your breath.
