Ivy Ledbetter Lee is considered by some to be the founder of modern public relations. The term Public Relations is to be found for the first time in the preface of the 1897 Yearbook of Railway Literature.
Write down the most important things you have to do tomorrow. Now, number them in the order of their true importance. The first thing tomorrow morning, start working on an item Number 1, and stay with it until completed. Then take item Number the same way. Then Num!, and so on. Don't worry if you don't complete everything on the schedule. At least you will have completed the most important projects before getting to the less important ones.
