Only you know what you know. Hear everyone but be thoughtful with how you take into account people's feedback. Try to understand why people have told you the things they told you, is there anything more to learn from it than just what they've said. Once you've processed it, objectively decide what you take & what you leave from external advice.
The most enduring piece of advice that has transformed my entrepreneurial journey is this: ‘Don't fear failure, see it as a stepping stone, a lesson to learn from - it's your greatest teacher, and it propels you to refine and perfect your craft, always pushing towards success with resilience and determination
