Once you realize, internalize it and are OK with it - you will experience freedom maybe for the first time. The truth is when you come right down to it: we are born alone, we live alone and we die alone. Nobody - no matter how much they love or care for you - can get inside you and know you! Not in this material realm. Most of us go through life not even knowing ourselves!
CORRECT ME IF I'M WRONG BUT, As I turn 43 this year, I have realised, as a man, no one cares about you. Not your wife. Not your family. Not your friends. Not your workmates. Nobody. People act like they care, but deep down, they don't. You are on your own. Always on your own.
