What's the biggest mistake beginners make?

After watching hundreds of aspiring builders, the patterns are clear. Here are the top mistakes:

1. Building too much, too soon (most common) You have a vision for the 'complete' product and try to build all of it before launching. Meanwhile, you're not talking to users and might be building the wrong thing entirely. Launch ugly, launch fast, iterate.

2. Perfecting before shipping Spending hours on the perfect color scheme while core functionality doesn't work. Users don't care about polish until the product solves their problem. Get it working, then make it pretty.

3. Avoiding the uncomfortable parts Skipping user research, avoiding asking for feedback, not reaching out to potential customers. The building is the easy part-the people stuff is what makes or breaks products.

4. Tutorial addiction Watching courses and tutorials without building anything. You learn by doing. Take a tutorial, then immediately build something different using what you learned.

5. Going it alone Not joining communities, not asking for help, not learning from others who are a few steps ahead. The solo genius myth is rarely how successful products get built.

6. Underestimating the learning curve Expecting to build production apps in your first week. Set realistic expectations: useful apps in months, not days.
