If you've ever tried to download a video from Reddit, you've probably ended up with a silent MP4 file. No audio. No error. Just a video that should have sound but doesn't.

# Why You Abandon Every React Project You Start (And How to Fix It)

If you look at your GitHub repositories right now, how many unfinished React projects do you have? Three? Ten? Fifty? You start with a massive surge of motivation. You run npx create-react-app or set up a new Vite project. You spend three days perfectly configuring Tailwind CSS, setting up Redux, and carefully architecting your folder structure. And then... you get bored. You hit a minor roadbloc

Imagine you run a bustling coffee shop. In the beginning, you take orders, make the coffee, and serve pastries all by yourself. It works perfectly when you have a handful of customers. But as the crowd grows, you become the single point of failure. If you are stuck making a complex latte, the simple drip coffee line grinds to a halt. In software engineering, this "one-person shop" represents a mon
