After years of success when single, i've become a defacto dating advice specialist for friends and family.
I hit the woodshed and went back to review some old materials for the benefit of a friend going through tough times after his girlfriend ended a relationship with him. David D brings together a host of speakers in this including evolutionary biologists.
His material is worth it, whether you are struggling in your current relationship or looking for new ones. Some of the information is dated (internet dating has evolved into quick swipe apps).
The social skills that many currently lack in younger generations could be well addressed with David D's material which is timeless for in person communications.
I read the workbook and listened to approxinately 18 hours of audio content that comes with it.
