Query: Write a letter to yourself

If you're having a bad and rough day, or if you are taking a nice peaceful drive on a sunny afternoon, I would suggest this, the Delfonics Greatest Hits, or any Five Stairstpes compilation. This particular collection contains songs that are so pleasant that you'll just melt when hearing them. Even songs with melancholy lyrics like "Toby," "Write a Letter to Myself," and "Have You Seen Her" sound so sweet to the Philly Sound arrangements and the Chi-Lites' harmonies cannot help but make you happy. So write a letter to yourself to pick this up.
