Worldly success- we all need a little- but books such as 'how to win friends and influence people', 'think big' and 'the habits of highly successful people' tend to miss the point. Simpler observation shows you only need three things- are you able to do a job in such a way as to achieve strong personal recommendation for it (notice the doing of the job is only part of this- in other words, can you convince people 'you're the man'); secondly- are you able to stage a party that people want to go to? (for whatever reason); and thirdly do you show gratitude for your good fortune?
And being able to point out the correct reasons for worldly success are no guarantee of achieving it...
