But statements such as "The hottest summer I've ever known" are meaningless, since in every one's life, one summer is going to be the hottest, and the longer you live, the more likely it is that this summer will be IT!
So it is with items for your monthly email newsletter (or "brag" at your local networking meeting, or ....).
In each week, by definition, there has to be a single event that qualifies as "the best this week"; there has to be a "worst mistake this week"; there has to be a "most glaring example this week", and a "best computing tip this week". Or month.
There are no excuses for failing to come up with a "best" or most-significant in any category you choose to name, for any period you care to pick, short of a few minutes.
Come now: What's the best compliment you've received in the past 30 days? And what did it tell you about yourself?
