I have begin to read some books from the Personnal MBA . First was getting things done. An interesting method of every day work and life management. You can manage this method with Google notepad ! The best thing I have learned so far is to clean my mind of "open loop" and note everything. I have read the book "Influence: The Psychology of Persuasion" which describe six common things in people psychologie. Like PersonnalMBA says : Knowing these natural psychological tendencies will help you in two ways: (1) you'll become more persuasive, and (2) you'll be able to identify when these tendencies are present, protecting you from being misled in the future. I am now reading "how to win friends & influence people" and my next books will be : The unwritten laws of business, the design of every day things and Making things happen. I am an addict :)
Self-education is the only kind of education there is.
