Your world is a reflection of your mind. When you encounter someone you feel is toxic, look within you. What inside you has attracted someone or something toxic? Once identified work on it. As you keep going through this process, your insides will transform in a way that you will start attracting only the best for you. But if we get stuck blaming my the other person for being toxic and only judge them, we are wasting our precious time and also we are not growing. It is our choice if we want to be stagnant or keep evolving.
