About this quote

Take that as a hard truth, not an excuse to avoid responsibility: stop explaining away behavior and stop making assumptions. Focus on what you control — clear questions, firm boundaries, and improving your own response instead of trying to read minds.

When to use it

• When a friend keeps breaking promises, remind yourself you don't ever truly know another person and stop excusing their pattern; call them out and set boundaries.
• Before trusting someone with a big task, use the line as a reality check: verify their actions, don't rely on imagined intentions.
• If you find yourself obsessing over why someone acted a certain way, say the quote to break the loop and focus on how you'll respond instead.
• In a work meeting, use the idea to encourage direct questions and facts rather than guessing at teammates' motives.
