I had to think about pinning this one as I dislike Mr. Emerson do very much. But this quote shows in a nutshell why I dislike him. If a reasonable person looked at this they would think it was about not burdening oneself with the mistakes and troubles of yesterday. Good. If a nutcase like Emerson reads it he screams hakuna matata I'm not dealing with anything I don't like.
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Philippians 4:6-7
