People often answer beginner programming questions with "just start building something," but that can be intimidating when you have never built a project before. How do you get started with a library whose autogenerated documentation has few or no examples? Is it reasonable to study other projects or switch libraries, or is there a better way to learn independently? Also, when a framework offers several ways to accomplish the same task—such as different approaches to creating a GUI—how can you tell which class, method, pattern, or implementation is appropriate, maintainable, or performant?

Imitating an existing example is a perfectly valid starting point. Try to reproduce it yourself, change parts of it, and then build a small project of your own. For libraries with weak documentation, look for tutorials, sample projects, API references, tests, and source code from experienced users. Experiment with tiny programs so you can isolate what each class or method actually does.
A useful mindset is “it depends.” The right GUI pattern or library feature depends on requirements such as scale, performance, readability, team conventions, and how often the code will change. When documentation is sparse, keep notes about what you try, test assumptions with small prototypes, and measure performance when it matters. Programming involves plenty of trial and error, and there is no shortcut that replaces hands-on practice.
As a beginner, focus first on making something work rather than proving that every decision is ideal. You’ll learn debugging, maintenance, searching for answers, and refactoring by fixing your own imperfect code. Later, study design principles, code smells, security, performance, and alternative patterns. Many choices depend on the project, so practices that are good for one application may be unnecessary or harmful in another.
You usually cannot know in advance that you’re doing it the best way. Build a small version, run into problems, and use those problems to learn what should change. Experience with the wrong approach is often what makes the better approach meaningful. There may not be one perfect solution, but you’ll gradually learn to recognize approaches that create unnecessary complexity or poor performance.
I once spent weeks building a dashboard before realizing the state-management approach was wrong throughout the project. Rewriting it went faster than expected, and the mistake taught me more than reading about the pattern would have.
