A useful idea in overcoming mental anxiety is the mind palace. Let it be a comfortable structure, holding the sum of all of your acquired knowledge, where people may decorate and reside in their own room. These perceptions of people could be close family, good friends, single-serving friends, inspirational figures, imaginary characters, or sworn enemies. You make the house rules and you’re the landlord. Shouldn’t the first rule be forbidding enemies from attempting mental trespassing?
