The Way of Men by Jack Donovan Summary(in 1 min)

True and that's exactly why Donovan wrote this book. To show just how important it is to develop this type of relationships with other men especially in modern day society.

Time management is not mentioned in the book, but there are plenty of resources about that. I recommend the 4 hour Work week by Tim Feris.

Also you could try developing this type of relationship with your colleagues by going on/planing company events.
