I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

Ten simple rules for developing good reading habits during graduate school and beyond To me, the most important are: Read often, read broadly (incl. older papers and outside your field), and learn to read some papers in detail and others more superficially (and quickly)
Ten simple rules for developing good reading habits during graduate school and beyond by Marcos Méndez
1: Develop the habit of reading on a daily basis
2: Read thoroughly to build a sound background understanding of your topic
3: Do not ignore the pillars of your discipline; read the classics
4: If you have to get familiar with a new topic, consider reading in chronological order
5: Avoid narrow-mindedness by reading beyond your discipline
6: Create a list of relevant journals
7: Not all interesting stuff will appear in articles; read books
8: Use a reference manager to keep track of your literature
9: Keep a long-term review for your own use as a way to remember what you read
10: Build your own library to make yourself independent and inspire others
