What advice would you give someone starting a business for the first time?

Focus on creating valuable content, engage with your community, and leverage personalized outreach. Test various growth strategies, but prioritize organic approaches for quality user acquisition. Be prepared for some tactics to not work, but persist and adapt.

Focus on solving a real problem, start small, and iterate quickly based on customer feedback to refine your product.

Research about what people need actually.

Find people smarter than you and just ask for free help. You might be surprised at how many people will help for free if you ask.

It really depends on the business. But if you mean Saas I would say talk to people and see if there is actual demand (if you are solving a problem).
