If you are referring to TWIY – The World Is Yours – than yes. Quite a while ago my first self published book was TWIY and I sold it for next to nothing! At the time I had no idea the book would become so popular. The original TWIY then turned into FYBR 1, then 2, 3, 4 since many others were becoming fascinated with TWIY and the volume of questions increased dramatically – TWIY to this day features large portions of the current ITSI and FYBR journals with TWIY being the originator of the many other journals that came along. If these are controlled in the right manner they will continue to convey the necessary trading principles.
