Sun Tzu

If you intend to start a business and you want to win all your battles, first you must prepare for war by learning from the best Generals. Get ready for the war with yourself and if you have time, with others. We all want peace, nobody wants war (I hope so), but if you want respect you need the power to be on your side. And only when you will have power, you are going to be respected and everibody will see who you really are.
The first place to look for, if you want to learn about strategy, is Sun Tzu: The Art of War. Sun Tzu was a Chinese general who lived between 722–481 BC.
Other books on this topic that I can recommend are "The Prince" by Nicollo Machiavelli and "On War" by General Carl von Clausewitz.
If you ever have to have a war, you will need the skills to end it in favor to your self only always. For that, learn the secrets from the book that tells you when the negotiation stops an the war begins. Only this way you will have complete control, and this can be achieved by reading the book: Guerrilla Negotiating: Unconventional Weapons and Tactics to Get What You Want (Guerrilla Marketing Series)
So, if you want to be a great entrepreneur and you did not attend a military school like Donald Trump or Robert Kiyosaki did, you should better study these books.
