Instructional Website

I'm having a difficult time choosing a topic for my Instructional Website. I have a few ideas but none are really too appealing to me. I want to choose a subject that actually interests me so I can use it later "down the road". I'm just a little distracted lately. I've been busy working on a community service initiative for my daughter's elementary school so that has monopolized a lot of my time. Plus, tonight I was informed that a student in my son's first-grade class is dying from a brain tumor. Very, very sad. Such a sweet little girl with so much life to live. I guess I'll try thinking about school tomorrow. Hopefully a bright idea will hit me when I least expect it.
