Marty, don't give up. Let your mind think outside the box. When I was stuck in the hubchallenge I reverted to some recipes. If you cook, or if you have a favorite recipe post it with a few words about why you like it or what is special...you get it.
Post a hub about a favorite author, why you like that writer, etc
Post a hub about your favorite holiday, a memory, a sport you played as a kid
Post a hub about your travel experiences...
Make a list of your favorite...songs, movies, sports, team, food, flowers, constellation...whatever.
It doesn't have to be Einstein material, and the word count doesn't have to be long. Good luck to you. BTW I wrote a hub at the end of the challenge about tips for taking the hubchallenge. Feel free to read it and use whatever you need to get a boost.
