If you keep a journal, you probably write the day's most noteworthy events in it, or the most remarkable things that happen to you.

Something is described as noteworthy when it's worth taking interest in it. Your teacher's enormous new beehive hairdo might be noteworthy to you, while her insight into the history of your town might be less noteworthy. The adjective noteworthy is a compound word made from note plus worthy; in other words, if something's worthy of making a note about it, it's noteworthy.
