Recently, I read about a speech that David Leuschen gave last October at his alma mater, Dartmouth College ’73. Leuschen spoke to the students at The Tuck School of Business, where he received his M.B.A from in ’77. Today, Leuschen is the founder and CEO of Riverstone Holdings and previously was the partner and managing director at Goldman Sachs. Leuschen shared with the students his secrets to success, which have been applicable in his life and business.
