Doomsaying can become a self-fulfilling prophesy,
as David Brooks points out. I want to point to
Fix The News, a website curated by Angus Hervey and Amy Davoren-Rose, that points out positive stories, and offers to send occasional emails (Which I enjoy receiving) that list some of its content.
Another positive (and totally woke) effort at making a more positive future is described in the document "New voices for a better society".
I would also point to previous MindBlog posts on the positive views of Steven Pinker. Nicholas Christakis, and Hans Rosling.
