Self-awareness is like great sex: everyone thinks they have a ton of it, but in reality no one knows what the fuck they’re doing.
The fact is that the majority of our thoughts and actions are on autopilot. This isn’t necessarily a bad thing either. Our habits, routines, impulses, and reactions carry us through our lives so we don’t have to stop and think about it every time we wipe our ass or start a car.
The problem is when we’re on autopilot for so long that we forget we’re on autopilot. Because when we’re not even aware of our own habits, routines, impulses, and reactions, then we no longer control them; they control us. Whereas a person with self-awareness is able to exercise a little meta-cognition and say, “Hmm… every time my sister calls me and asks for money, I end up drinking a lot of vodka. That might not be a coincidence,” a person without self-awareness just hits the bottle and doesn’t look back.
