This is pretty good advice overall. One small change I suggest is to take it easy on Design Patterns and the like. I’ve seen people in OPs position (general smarts but limited production experience) turn into architecture astronauts and start overengineering everything. It can be useful if you’re working on a legacy codebase and need to understand the jargon that can appear in [possibly overengineered] existing codebases.
