The same is true for seminar and lecture titles and the professional titles and brief autobiographies of the people involved. Notice the titles, but reserve judgment. Some good books and people are self effacing. Some mediocre books and people crow very effectively. Judge carefully books, seminars, people who promise you the answer to success.
Social problems are complex.
And careers are decidedly a social problem. Judge carefully the presence of hype or hard sell. Good material still needs good marketing. If you encounter excessive selling, chances are the material just won't stand on its own. We like humor.
