I first learned of the Direct Line program through Jeffrey Gittomer many years ago.
Thanks to EBay, I was able to acquire the cassette tapes and have listened (and relistened) to Earl’s ideas for many hours. The bibliography he presents within has proven to be a rich source of additional learning. Anyone who is a serious student of life will benefit. Sure, some of the material is now dated, but the rest is pure gold.
To see that this program is now in print form is wonderful. I plan to give a copy to each of my children. It’s that good.
