• relying on shared mutation
• treat the compiler as something trying to help
• ignoring proper module organization

You have to unlearn a few habits.

1. Writing Rust code like other languages
2. Neglecting the most important 20% of Rust. Trying to learn everything at once: you don't need to learn all at once. Focus on the 20% that gives the 80%.
3. Being a productive procrastinator: watch a video or read a blog post.
4. Thinking you can vibe code Rust like JS...

Hands on practice! The programmer has to internalize the concepts of Rust. Getting a grasp is not enough.
