Look around you. Are the people you hang around the most the type of people that bring you down, always see the negative side of things, never have anything nice to say, crush your dreams? They have zero ambition to better their own life so they belittle you for wanting to better yours? Or do you hang around the type of people who challenge you to new heights? They empower you with character building morals and values? Lift you up when you need it? Do they help you to see there is a way to stay stuck and use every excuse imaginable to remain in a rut, or do they move forward in life and encourage you to do the same?
Whether you believe it or not, you being to emulate your "average of 5." It's just the law of nature. If life is not taking you down the paths that lead you to your dreams, then perhaps it's time to change the 5 people you hang around the most. Look for those that are doing the things you want to do. Find a positive minded mentor. Read books about people that accomplished goals in their life that are similar to yours. Sure your backgrounds may be different, but don't focus on excuses as to why you can't, focus on solutions as to how you can!
What type of person do you want the world to see you as? Who is it that you want to become? Are you the best version of yourself there is? Are you living your life as the highest expression of yourself? When it comes to your "average of 5" look around you and choose wisely.
