Haters occur in proportion to admiration. Doing anything notable will generate both positive and negative reactions of similar intensity.
It’s impossible to be a life-changing presence to some people without simultaneously being a complete joke to others.
The best response to hate is to simply improve yourself so much that the hater’s criticisms become self-evidently false and empty. The best revenge is to be so undeniably good that there’s no need to ever respond.
How many things are you doing in your life right now to get back at somebody or prove them wrong? What would happen if you stopped?
Let go of the desire for revenge, validation, or vindication. Try focusing on your goals simply for the sake of your goals. See what that feels like and let me know.
