Best books to learn Quantum field theory, in order
QFT is notoriously steep because it demands fluency in quantum mechanics, special relativity, and classical field theory all at once. A good path is patient and layered: canonical quantization of free fields first, then interactions and perturbation theory with Feynman diagrams, before renormalization and gauge theory, so the machinery is built up rather than dropped on you fully formed.

- How should I approach learning quantum field theory?
- QFT is notoriously steep because it demands fluency in quantum mechanics, special relativity, and classical field theory all at once.

- What's a good book to start quantum field theory with?
- A strong starting point is Gauge theory of elementary particle physics by Ta-Pei Cheng. The ordered reading paths above show exactly where it fits and what to read next.
