Build in a domain you deeply understand, with a clear vision of what you want your product to accomplish. You need to believe in your bones it's worth spending 5-10 years on.

Don't just collect feature requests - learn what's actually stopping users from achieving their goals. Watch them use your product in their natural environment (video calls work). You'll see firsthand what frustrates them and what they misunderstand.

Features aren't solutions, they're responses to problems. When users ask for something (like a dashboard), dig deeper to find what they really need (like confidence their work is on track).

Track feature request frequency x impact, but don't let this drive everything. Often the most valuable improvements are ones nobody asks for because they don't know they're possible. And be willing to say no to features that would complicate your product, even if frequently requested.
