AKA a recipe. You can follow a Michelin starred chef's recipe all you want, but you're not getting your own star that way. You actually have to learn to cook. But recipes can still be useful anyway.
Novelty: If the person you're copying isn't doing something novel (like playing Bach on piano) then in all likelihood you will get the same reward did. If you copy someone who built a CRUD app for their company and do the same for yours you'll probably get the same reward.
Context: If you make a delicious meal for yourself, you and your SO, your coworkers, your friends, or the public the rewards are all different and context can sometimes be complicated so it's really hard to know if captured it.
