What makes you think that not a single one of your thoughts are not unique? It seems likely that many of your thoughts are unique. Especially as they relate to your immediate perception of your environment- you have a unique history, and a unique position in the space/time/matter organization. Therefore, many of your thoughts will be unique.

Now if you move towards abstractions, such as "What a nice color green", then others will have thought the same abstraction about other green objects. But your own perception of the specific, it is unique, and your own apprehension of that specific, also is unique.

Even towards abstractions, I see some new ideas even here I have never seen elsewhere. But also, I think there are many good ideas from the ancients which have yet to be fully explored (at least the greeks).

I will attempt a few unique abstractions for you:

Culture is a form of sunscreen which blocks the most novel ideas from penetrating into the collective consciousness, until a light so bright and popular can burn the idea through to create a new perception of reality.

Your own thoughts are your best and worst friends. They can lead you to places no one has gone before, but also keep you in places where you can not escape.
