Some other things that you could add to your tool belt are testing and testing frameworks, documentation "standards" (standards being defined by your org), and telling when a class, function, or script is starting to get to large, and needs to be broken out. The best ways to learn these skills is on the job. Since competition is fierce I would look to some sort of professional system that allows you to begin to ask these questions. Like working in a tech based call center, or working in a QA department, or taking some courses at a local community college. Going to reddit, and stack overflow might not be the best way to get thins information as there are a lot of people who don't post useful insights or information there. Youtube would also be a great place to get some exposure to these skills, just finding the right video.
