Hate will only poisin the mind of the person who uses it to accomplish any goal in life.
Concentrating on hate with your conscious mind will send messages of hate to your subsconsious mind, and since your subconsious mind doesn’t have the capacity to hate, it will help you to mirror the characteristics of the person you are so hell-bent on hating. In the end you will end up just like the person or people you hate.
If you used the same theory but instead of hate, you apply your conscious mind to selecting the characteristics you love in other people, you will end up mirroring all the best characteristics you see in other people.
What you concentrate on is what you will become; the question you need to ask yourself is:
Do you want to become somebody you love or somebody you hate?
