just as many of you, I am familiar with many Nightingale Conant authors. I actively read those books in the beginning of my success story. At some point I stopped and decided to implement instead of consuming yet another material.
Now I am at the point where I have already achieved a certain level of success and welcome some guidance on how to continue. I noticed that all books I knew so far were about quitting your job and starting your own business. Now I would like to get some inspiration on growing my business.
Just to name a few concrete topics: one of my challenges is that it is hard to find the right people, who are self-guided, determined, consistent, trustworthy, loyal and competent at once. It is also challenging for me to find a fair conditions for partnership with people. How do you know if one is good in advance?
What authors and titles would you advise?
Stop reading motivational crap and read text books that teach you to do solid analysis. The author does not matter. All competent authors will use the same math and other analysis techniques.
I consider all of the authors on the site of the company you referenced to be worthless charlatans that are just trying to get your money. They are selling snake oil.
