Online, anyone can contact you, not just the highly relevant people in your physical vicinity. They have questions about their priorities—not yours—when it’s convenient for them—not you. Every time you check your email or another message service, you’re basically saying, “Does any random person need my time right now?” And if you respond right away, you’re sending another signal both to them and to yourself: “I’ll stop what I’m doing to put other people’s priorities ahead of mine no matter who they are or what they want.”
