Why Didn't I Think of That?

Doesn't it seem like when all of the good ideas are already taken, BAM!--something comes along that has everyone saying "Damn, how come I didn't think of that?!" Why is this? Why do such inventions leave us feeling this way? I tend to think the main reason so many great ideas are overlooked is assumption. Assumption, as in that it's such a great idea, someone else has to have thought of it already and is in the process of trying to develop it. Another reason is the overwhelming feeling of not knowing where or even how to begin.

The good news is that with thorough research you can find out the things you need to know to make sure no one else is "in your lane," so to speak. After all, we live in a time where virtually no one is anonymous, especially if they are running a business. In other words, technology has allowed almost everyone to be accessible, especially those who own and operate a business. With that said, the chances of someone else working on the very same idea you have and there be no researchable information or record of it is very slim. So if you've got a great idea, don't sit on it. Do your due diligence and if the coast is clear, go for it.
