Finding success in a new niche can take time and persistence. Personally, I'd give it at least 6 to 12 months of dedicated effort before considering a change. During this time, it's crucial to analyze what's working and what's not. If you're consistently putting in effort, experimenting with different strategies, and still not seeing results after a year, it might be worth reevaluating your approach. Sometimes, tweaking your marketing tactics or seeking guidance from successful marketers in that niche can make a significant difference. Remember, every niche is unique, and what works for one might not work for another, so staying adaptable and open to learning is key.
