Few days ago, I randomly stumbled upon a letter that F. Scott Fitzgerald wrote to his daughter in 1933 about things to worry about. Worry about courage, worry about cleanliness, worry about efficiency, and so on… His letter stroke a chord in my brain and made me think of all the small things that occupy our minds on daily basis and prevent us from moving forward. The list is longer for things not to worry about. Definitely a must read. You may read the entire letter here.
