Thats what is most interesting about human innovation and creativity in general. There are very very very few original ideas out there. Almost any idea anyone has had, a large number of people have had it. And most innovation is just tiny tweaks to existing formulas, over time.
In fact, if you understand the backstory behind most innovations, you realize it really wasn't all that impressive. There were many proposed models for flight before the wright brothers. They stumbled upon the right mixture. Modern day car fuel engines have essentially evolved over centuries of perfecting "torches" (fire and gas to create heat)
The people who make history are simply the first ones to act upon these thoughts. So, you become a content creator/culture setter, by simply being the first one to vocalize your thoughts.
Let me share an original thought I just came up with. As Paul Graham recently wrote, you can be an accidental moderate because you disagree with people out of intellectual honesty and critically analyzing the positions in an effort to learn something. So people like that contribute to steering conversations towards the truth.
(PS: Yes, what I wrote above was ironic on purpose.)
