Don't write publicly if you don't want, but:

What did you have for breakfast this morning? How did you get home from work today? Tell me about the last time you went grocery shopping.

Etc. Pick these or any other asinine, boring topic and try to make it interesting. IMHO, it's good to do this in two steps. First, just sit down and write, continuously, without judgment or editing, write a lot. Then, figure out how editing can make it better.
