I believe that life is too short to waste your energy or precious time -as you very well said- for enemies in general.. Since they do exist, I prefer not giving them any feedback, unless they step on my feet.. Even though they say that "you should keep your friends close and your enemies closer" I prefer to keep toxic people entirely out of my life..

Regarding the random ones who try to mess with my karma, I don't even bother anymore cause they don't deserve it.. :)
