Once you can connect to external data, the next question is:
"Can I remember what users did?"
That's state.
I built a choose-your-adventure game.
Every choice stored on-chain.
Every decision affected the next.
Different paths for different users.
This is when coding gets real.
Not just "do this function."
But "remember this, track that, handle edge cases."
It's harder.
It takes longer.
And you learn 10x more.
Your next project?
Make it remember something.
