Quote from Specterx:
The book is somewhat interesting but won't change your life. His basic conclusion is that 'lucky' people exhibit certain behaviors and attitudes that 'unlucky' people tend to lack: openness to new experiences, constant pursuit of new opportunities, readiness to take risks (pursuing a dream, starting a business, uprooting and moving across the country for a potentially better job, etc.), and of course a high level of sociability.
The most interesting bit I remember was when he discussed a survey of Princeton graduates at their 25th reunion, which found that those who reported the greatest life satisfaction had changed jobs much more frequently, and often started several businesses, compared to those who were not particularly happy with their lives.
