I need to re-build my MVP - Lesson learned. let's start again

I built a health tech app pretty much fast without ANY market validation, But only based on my experiences and assumptions, thinking all ends will just match up like magic! The scariest part is here! I conducted 3 user interviews while attending the YC startup school and 😅 it seems like my MVP has missed the most important part of the problem. Amazingly all through the development process, I kept avoiding the thought that I might be sliding out of topic. And my team kept sounding that alarm but... ❤️Lesson 1 Avoid pride even with yourself. Listen to the positive inner voice ❤️Always consider your teammate's advice ❤️ Go through the process it is worth it. See in you in next 4 weeks !
