When you are pursuing your greatness, you don't know your limits, and as a result, you must surround yourself with people who can make you grow and stretch, even if it means losing some of your friends that add no value to your growth. When you are pursuing greatness or excellence, we all need someone to help us see and think outside our narrow perspective of what is.
We need someone who understands our potential even when we haven't yet accepted it ourselves. Surround yourself with people you can learn from, who can raise your vibration, who can help you become the very best version of you because your time is short on this earth, and it makes no sense to limit your growth base on the limitations of others. When you do this, it will elevate you to a new level of success.
