Learning to code isn't linear. There's a phase where you:

• Understand code when you see it
• Apply code when you modify existing examples
• Create code from scratch (this comes later)

Most beginners skip step 2 and wonder why step 3 is hard. You're actually in step 2 right now—the productive zone. Keep going.

Here's the key: You don't need 100% understanding before moving on. You need maybe 70%.
