No one cares about your life as much as you do.
I don’t mean that nobody loves you or thinks about you.
But when you think EVERYONE can see the pimple on your chin and the stain on your shirt, and the guilt on your face, just remember that in that thought, you are being self absorbed.
Everyone else has their own bad hair day, or ripped jeans, or tiredness or problems that THEY are focused on. Their world doesn’t revolve around you. They are more worried about their own stuff than about yours.
So get over it!
