A maioria dessas ideias será mais ou menos **independente**, e na maioria dos casos você só precisará estudá-las se elas se aplicarem diretamente ao **seu projeto**.

Se algo parecer interessante e útil para o seu projeto, vá em frente e dê uma olhada. Caso contrário, você pode simplesmente ignorá-lo.
