If you surround yourself with people who are negative, insecure or destructive, it will affect you. Regardless of your strength as an individual, you are not immune to a constant surrounding of negative energy or bad influence. If you want to have greatness in your life, surround yourself with great people. If you strive to be a happy, fulfilled, honest, confident, empowered and principled person, surround yourself with people who are the same. It's selfish and heartless because if you are influenced negatively by someone, it will affect how you are with the people who love you. Choose your company wisely. Be relentless with surrounding yourself with those who bring out the best in you.
