I'm a student founder struggling with market research. Is there anyone willing to teach me how to do it properly?

Hey everyone! I'm a third-year Computer Science and Design student from India, and I'm trying to learn how to build a real software business. I've been working on SaaS ideas, and one thing I'm genuinely struggling with is market research and customer discovery. Everywhere I look, people say: Talk to potential customers. Validate your idea before building. Find your target audience. Build in public and grow a community. But as a beginner, I honestly don't know how to put these things into practice. How do I find the right people to talk to? How do I discover problems worth solving? How do I conduct customer interviews? How do I know whether a problem is worth building a product around? And how do I start building an audience when nobody knows me? I'm not looking for someone to validate my idea for me or give me a shortcut to success. I'd genuinely appreciate learning from someone who has done this before — perhaps a founder, indie hacker, product manager, or someone experienced in customer research. If you're willing to share your process, recommend practical resources, or even guide me through a small research exercise, I'd be extremely grateful. I'm willing to put in the work. I just need help understanding how to do the work properly. Thank you! 🙏
