When genuinely engaged in real-time, e.g., present moment awareness, all human interactions, friend or foe, will appear silly and, perhaps, a bit mundane. You may also find yourself giggling that you were once so foolish.
Live with abandon. You cannot fail at life, nor will you be graded in any way for anything you do. Only humans carry around a red pen. Have fun, not fear. Love your friendships and feuds. It won’t affect your success in life, but it will make it more enjoyable.
