Blogging topics

Why is it that when I am not online I can think of fabulous topics to blog about -- profound insights into the world around me, observations of common humanity, thought-provoking questions...then when I sign-on the best I come up with is a laundry list of my boring life?? Oh, well, one day when I have DSL I'll sign on more quickly and more often so I'm more likely to catch those fleeting thoughts.
