The odd thing about life is that you are really alone. You are born alone and you die alone. You do pick up people along the way and love them, hate them want to be them but in the end you are your self. So it is reasonable to take care of that very same self.
We also have an internal dialogue that runs all the time even in sleep. It tells us how we are doing in the world. Sometimes it lies to us. It tells us that we are less than we really are. Pay no mind to that little voice. Listen to the one that loves you, that knows you are unique, one of a kind, special to the world.
The universe only makes one of a kind there are no others like you. That my friend makes you special and worthy.
You will leave this world alone that doesn’t mean you can’t leave it better than you found it.
