Advice from billionaires is subject to survivorship bias. Luck and timing have a huge multiplier effect on one's personal wealth. So, personal wealth is not proportional to the quality of message. Most extremely wealthy people I have come to know are surrounded by "yes men" that thrive by stroking their ego. But, wealth does provide a degree of freedom that gives one time for reflection and introspection. Personally, I believe a diversity of perspectives is healthy, while hero-worship is not.
