What are some things that every computer user should learn? What things do you wish every computer user knew? What are some of the biggest benefits that individuals and/or society could reap if computer users learned these things?
Please boost, I honestly want as many serious answers as possible. Feel free to answer variations of the question for different levels of "computer users", such as programmers, office workers who use a computer 4+ hours per day, phone-only users, etc.

The command line is not to be feared but is in fact the most intuitive interface imaginable.
Need help? Try `help` or `man`. Need an option for a program? Try `--help` or `-h`. Especially on programs this is way easier to find that feature than opening a browser and searching. Need to find a program for a topic? Try `man -k <topic>`

* `man man` to see what the numbers by the manpage stand for
* `man $SHELL` to see all power at your fingers
