Megyn Kelly (age 45) is releasing her memoir book this week. Joe Buck, the sportscaster, recently published his own memoir.

These are people that have a lot of life still to live.

My feeling about memoirs is that they should be written by people who are looking back at a full life, not people who are half way through and still have a lot to do and accomplish.

Is memoir-writing for younger people simply a naked money grab? Is this a big ego thing? Why are younger people writing their memoirs when they haven’t done all that much?
