SMS is not a manual on how to persuade someone to buy something they don’t need or want – it is not a book on manipulation.
The SMS method simply doesn’t work like that; it actually demands certain values and a level of transparency.
Essentially, it takes a brave approach to sell openly which is both sustainable and pure.
Indeed, you will find that the murkier things get ethically, the more you’ll have to distance yourself from the method. Like most pure systems, it just doesn’t work well in dodgy situations.
