Like some cosmic energy is pleased when you "get" that it's been trying to subtly let you know that "Yes, you should be a train conductor and not a surgeon."
What about when you don't "get" it? At what point does that cosmic energy (or God) get fed up and quit trying to be sublte and slap you in the face with something you obviously didn't pick up on yourself? How exactly does that go down?
Do you see those signs?
Do you look for those signs?
What have you accomplished or failed at in your life when you saw and took to heart said "signs?"
