This book is a product of practical experience in my place of work ie Kenya Revenue Authority and Treasury where I worked for thirty-seven years. This I did in different capacities and programmes. I retired as Assistant Commissioner and manager in Policy Unit Technical, Head Office. Before that, I headed different programmes and gained experience in business administration and NGO practices and procedures. I discussed with successful CEOs of diverse companies learning the causes of their success. Currently, I am a lecturer in Kenya School of Revenue Administration(Kesra) a constituent university of JKUAT.
