I recently learned the MERN stack and want to build a full-stack website to reinforce what I've learned. I have roughly one month available, so I need something focused enough to finish but meaningful enough to keep me motivated. I'm not interested in building an e-commerce site because that feels overdone and I'd probably lose interest. How do you decide what project is worth building, and what kinds of projects have worked well for you?

Since you’re learning React and Node, you could build smaller pieces instead of forcing yourself into one huge application. Make a few polished components, such as a dashboard, editor, search interface, or data visualization, then combine the best ones into a small full-stack app. That keeps the scope manageable for a month and gives you practice with the core tools.
Be clear about what you want to get out of the project before choosing it. Do you want to practice authentication, APIs, database design, deployment, or user interface work? Once you pick two or three concrete learning goals, the project ideas become much easier to narrow down. A simple app that finishes is more valuable than an ambitious one that gets abandoned.
Try not to choose a project only because it teaches a particular technology. Pick a goal first, then learn whatever you need along the way. A larger personal project can naturally introduce databases, authentication, deployment, networking, and other skills without you having to plan every topic in advance.
I usually keep short notes, save useful links, and write down the decisions I made. You won’t remember every detail, but you’ll remember how to find and relearn the important parts.
Another good approach is rebuilding something you already understand. If you have a spreadsheet, notes system, hobby tracker, household tool, or other process you use regularly, recreate it with the new stack. Knowing the problem domain lets you focus on learning the framework instead of inventing requirements from scratch. Even a deliberately simple tool can teach you a lot if you take it through database design, frontend work, and deployment.
Start with a real annoyance or recurring problem in your own life. If the project solves something you actually care about, you’re much more likely to keep working on it. It doesn’t need to be a completely original idea—just useful or interesting to you.

That makes sense, but how do you keep track of everything you learn when a project takes you through so many different areas?
