What’s the best way to practice writing and improve over time?

I’ve been wondering, what’s the best way to practice writing and actually improve over time? Should I focus on writing every day, or is it more about quality than quantity? I’ve heard that trying different styles could help me grow, but I’m not sure if I should stick to one style and refine it. Also, how important is feedback? Should I share my work more often to get advice, or is it better to work on it privately until I’m more confident? I’d love to hear how others approach writing practice and what’s worked for them!
