Consider the following from people smarter than me:
Charlie "Tremendous" Jones prediction is that "You will be the same person in five years as you are today except for the people you meet and the books you read."
Ken Coleman, in his recent book, The Proximity Principle, argues that the most important determiner of your success are the people in your circle.
Andy Stanley's mantra is that "your friends determine the quality and direction of your life."
Jim Rohm claims that we're the average of our five closest friends.
Here's a few questions to audit the quality of your inner circle:
What are my values and ambitions?
Do the people closest to me share with or support my values?
Pick two habits of two of your close friends - if those four habits were your habits for the next year, would you end up in a better place than you are now?
Whose advice and input means most to me? Are they a trustworthy guide?
Am I the kind of person that makes the five closest people to me more effective? More encouraged?
What can you do today to surround yourself with the people who will encourage your success, support your growth, and propel you into the future you desire?
