Before Product/Market Fit, you have to be honest with yourself about something. You don't know what your product is, and you don't know who your customer is. You have a range of options on both sides, and your job is to find the right match.
If you lock in on one too soon, you're blinding yourself to your other options. Be aware of how you use your tools. Be aware if they're narrowing your vision rather than expanding it.
You're more likely to find a match if you maintain a wide view of options on both sides.
