Many creative people like inventing or improving upon things, but it is often hard to discover what needs to be invented or improved. Here are three common ways that you can discover these unmet needs.
1. Interview or observe your target consumer. For example, you might talk to a bunch of teachers to see if they have any problems that you could solve.
2. Imagine yourself in their shoes. For example, you might pretend that you are a teacher and see if you can find any unmet needs.
3. Use yourself as the consumer and keep track of your own personal unmet needs.
Whichever method you use, a great way to discover unmet needs is to keep a bug list. Any time that you notice something that takes too much time, is complicated, or seems inconvenient to your consumer, write it down on your list. You can then refer to your bug list later to see if it sparks any ideas for inventions or improvements.

"Ordinarily I am not given to long speeches, nor ever before had I descended to bombast, but I had guessed at the keynote which would strike an answering chord in the breasts of the green Martians, nor was I wrong, for my harangue evidently deeply impressed them, and their attitude toward me thereafter was still further respectful." -- Burroughs, Edgar Rice
