Can you pronounce? If you don't recommend enrolling in a Spanish training class first, after all, the first and most important step in learning a language is pronunciation. Whether the pronunciation is standard or not has a great influence on future study: the mouth shape and the position of the tongue are very important, which cannot be mastered by self-study. As for the textbook, Modern Spanish is the most classic textbook with a very systematic grammar. Generally used by novices.
