Let's have an honest conversation about passive income - what it really is, what it isn't, and how large language models are creating new opportunities for everyone, even beginners.
Passive income isn't:

• Getting rich overnight
• Completely hands-off money
• A replacement for initial hard work
• Guaranteed success

Passive income is:

• Money that continues to flow after the initial heavy lifting
• Income that requires minimal ongoing maintenance
• A way to scale your time and effort
• Building assets that work for you while you sleep

LLMs like ChatGPT and GPT-4 are everywhere these days, but most of us aren’t using them to their full potential. Sure, they’re great for answering random questions or automating some boring tasks, but did you know they could actually help you make some extra $$$ on the side? From creating and selling things like eBooks or AI-generated art to setting up automated consulting, there’s a ton of ways to turn these tools into money-makers. The catch? You just need a bit of creativity and a game plan. Let’s look into some cool ideas to help you get started!
