Feeling the need to share everything nowadays keeps everyone creating generic things. Sharing things discourages originality. Because with originality comes judgment. And with judgment comes doubt, and nobody likes to doubt themselves. It's easier to conform to a general creative without doubt, so most people do. And then, because of this, most people are creative under these pre-conceived impressions.
Nowadays, people think, "What's the point?" because what incentive for most people's creations are likes on Instagram or Twitter. But there is beauty in creation, just the act without thinking of likes. In fact, most of the best art and music throughout human history has been written by people in silence and then discovered afterwards.
Rarely did people experience fame like they do today. There was no instant gratification feedback loop like there is on smartphones for writing music or a book in the past. But that's what made everyone much more creative. They experienced their art and created things with much more attachment.
This post is not just for me; I speak to an audience in my head when I write it. I rarely write things for myself; I share most of the things I post here or on Twitter.
