In this booklet I am analyzing classic book 'The Art of War' by famous writer Sun Tzu through the lens of my theory of Common Points. In all struggles of life, the common points play the central role. They are the cause an activity or catalyst of an activity in competition. For example, in business means of profit, are common points between competing firms. Although, Sun Tzu analyzed war, I have reinterpreted the rules, tactics and strategies he gives us as guidance for competition in any sphere of life. The book present a system of 21 points for winning any competition based on common points and Sun Tzu. If you are a businessman, a politician, or a social worker this analysis can show you path to success.
