Start with the absolute most simplistic structure, or no structure. Starting from "Hello world" is OK! (ie. starting in a new programming language) Keep in mind you can always start over, especially if you componentize your work! As you prototype, or just design by drawing on whiteboard, learn your domain and gain ideas what would improve your initial lack of design. Iterate and refine when cost effective to do so, not sooner. If still on whiteboard, you could benefit from implementing rapid no-code solutions before diving into any code at all! Resist committing to structure, unless your experience and insights into the domain require it and you see clear benefits from doing so. Deconstruct structure you find bring unnecessary complexity, as well as build on structure when doing so clearly brings leverage. Care for your code.
