You need to open yourself to your world. However small you might think something is, it is something someone, somewhere, would like to know.
Edweirdo, for example, wrote a hub 'how to tie a bow tie'. http://hubpages.com/hub/How-To-Tie-A-Bo … ep-By-Step . Now there are many people in this world who would like to learn this and seek this on the internet. You have skills that you take for granted, whereas others want to learn this. Look at what you do and share it.
This is what producing good, niche, content is about - providing something useful to share.
I also find that some of the best things I have ever done were while I was in the process of learning something new. The confusions and misunderstandings were all still fresh in my mind, and that helped me explain concepts better.
Try using Google trends. Sometimes that's really helpful and enables you to find very good topics. It's at www.google.com/trends
Another thing, especially now with the Google Instant search, is to go to Google (or Bing, etc.) and type in random letters. Sort of similar to GalleryogGrace recommending the dictionary. If you use Google Instant it just auto searches as your changing your word combo, even if it's just a letter. Great ideas there.
Anyone else feeling discouraged to keep writing here due to plummeting hub scores?I know they shouldnt matter, but I do take it personally when I see my hub scores plummet overnight. I know a lot of you have noticed...
