How do I sell 10k books in a year?

I’ve been thinking about this goal, selling 10,000 copies of a book in one year. It sounds big, but not impossible if you really push it.

I’m curious how authors or marketers here would approach it. Would you focus on Amazon ads, building a social media audience, or maybe going heavy on email marketing? Some people say TikTok (BookTok) is huge right now for book sales, while others swear by podcasts and blog features.

Has anyone here actually hit big numbers like this? What was the strategy that worked best? I’d love to hear real experiences or even realistic breakdowns of what it takes to move that many copies.
