Suggestions Needed

I need suggestions. I'm freelancing with How To articles and I need suggestions. So far 9 are approved and I've written the article. Examples are: How to get a replica item into the country legally, how to test a two slot receptacle, how to feather dust, how to decide on getting a saltwater tank, etc. Stuff like that. How to have fun in The Bahamas. You get the idea. The problem is, some of the suggestions I have someone else has already done. That's why I need your help. What is it that I can do that might help others? What's a how to item I can write? I know how to do a ton of things but I want to think of others to add. :)
