When you're building and sharing your project (#buildinpublic), especially if you're working alone, many tech projects don't succeed because they lack good marketing and sales.<p>So, what's the solution? Think about the problem you're solving. If you really get what people need and have a clear idea of the problem, you've hit the jackpot. That's called finding a "product-market fit."<p>Now, as you work on your project, pay attention to the fact that your main issue might be that not enough people know about it. So, as you build your project, also create tools and services that help with marketing. Make these tools for yourself first. If they help your project grow, that's a win – even if no one else uses them. If the tools don't work, try again. Keep improving until you find what clicks for your project.<p>Here's the big idea: Sometimes, the tools you build for your own project end up becoming a successful business on their own. But to get there, you have to be your own customer and really feel the problem. So, focus on your main project, knowing it might not work out, but also build tools and projects that help it grow. If the main project doesn't take off, these tools might become your main money makers and the core of your business.
