Don’t get pulled into arguments or debates over things that don’t matter to you. Be prepared to lose some battles by biting your tongue when needed or by compromising on things you don’t feel strongly about so that you can “win” the things you do care about. If you nitpick every little thing, always trying to win every argument, your words will carry less weight when you actually need to “win” an argument about something you care deeply about.
If it doesn’t matter to you, or if you don’t have a strong opinion about something, don’t get worked up and bent out of shape when discussing it. Ask yourself how whatever it is you’re talking about actually affects you and your loved ones. If it doesn’t have any major repercussions, let the other person do what they want without you trying to force your advice on them.
