No one gets a handbook upon turning 18, complete with all the rules they'll need to memorize and competencies they'll need to acquire.
Somehow you're just supposed to know that you should have more money coming in than going out and you shouldn't wear a fuzzy orange sweater to a job interview.
Fortunately, we've put together our own handbook of sorts, which lists many of the skills you'll need to survive as an adult in the modern world. It's based on the Quora thread "What are some of the most useful skills to know?" as well as scientific research and expert opinion.
1. Accepting feedback gracefully
"For most of us it is hard to hear how we made a mistake or could have done something better," writes Quora user Pedram Keyani. "An amazing skill (which you can learn through practice) is to set aside your emotional response in the moment and focus on the information presented to you. Some of it will be valid and some of it invalid but let your brain decide that, not your ego."
Depending on what kind of feedback you're receiving, there are different strategies for responding with a cool head. For example, if your boss points out what she thinks is an error and you're not sure she's correct, you can say, "I hadn't thought of that, and I'm going to look into it right away."
