This short video below is a quick 30-minute interview with the founder & CEO of Stephen Schwarzman.  The interview is good, but what is great is Stephen's book, What it Takes.  On this page you'll find a picture of this book on Audible and a link to that book, make sure you buy it and listen to it whether you have time to stream this video right now or not.
What I have learned from Stephen is that you must clear out mediocrity, only say yes to really big, unique well-timed ideas,  and to not underestimate the power of buying businesses with inexpensive debt.  Blackstone has two values, 100% excellent and integrity, and with that Stephen has grown a $36B net worth.  I hope you find this video and more so is book as valuable as I have.
