“according to research by social psychologist Dr. David McClelland of Harvard, your “reference group” determines as much as 95% of your success or failure in life.” – The Compound Effect (127)

this doesn’t mean that you should surround yourself with people who are just like you. this doesn’t mean to surround yourself with just the most successful people. this doesn’t mean to surround yourself with just the smartest people. i believe more important to your success is surrounding yourself with just positive people.
