No matter how many times a snake sheds its skin, it will always be a snake. 

Do not allow the same person to fool you more than once. Depending how you get fooled, learn and grow from it and definitely forgive but never forget what that asshole did to you. It’s unfortunate what people can do to others and how they scheme instead of putting the work in themselves. You on the other hand should continue down the path to success and let the snakes go ruin someone else’s dreams. Make sure you are aware of these eyes of people and if you can foreshadow these types of behaviors, then distance yourself right away. They are snakes for a reason and leave it at that.
