"An unexamined life is not worth living."(Socrates) When living life we notice things that mean the most to us. But when we examine our soul and nature, we can not possibly, 1) give this job to somebody else no matter how well they know you, and 2) you can not attempt this the same way you would when you are examining, let's say a sandwich. When examining the soul and your life you can see and perceive things that no aunt or grandma can see. You need to go about this agility, precision, and accuracy.
