Never let it appear that something bothers you. Never let on that you have fire burning in your gut. Be rebellious, but only about such causes that make you seem correct and “right”. You may look into your backyard or your neighbor’s, but do not look inside yourself. Do not look there. There is nothing to see. Likewise do not express thoughts that might distress others, prompting them to look inside themselves. Do not do it. Generally, try not to say anything at all. You may speak, of course, but do not actually say anything. Maintain a semblance. In time, this status quo will solidify and therein you will carve out a life.
This is how it’s done.
