You’re Not the First Person to Think of This
That’s actually a very comforting statement. It can be discouraging to think that you aren’t totally unique, but knowing that someone else has had the same idea as you means a few more things: This idea is important enough that others are thinking about itSomeone out there can help you extend on this idea (because they already have)In the future you can help someone else who thinks of this Being the first or the original just isn’t that important.
