    7. Writing code is a skill that needs to be developed like any other craft. Start simple, and do it. Watching other people writing code isn’t enough. Adjusting other peoples’ code isn’t enough. You have to write your own code, that solves your own logistical problems. They can be made up problems, but the practice of problem-solving is the fundamental basis of coding.
