Feedback will either be plentiful or non-existent, but once it’s plentiful, don’t ever take it for granted. Maintain a conversation with customers and always dig deeper. Be thankful they took the time to share, and be honest about how you plan to act–or not act–on their feedback.
It’s hard when someone criticizes the work you’ve poured yourself into, but you mustn’t take it personally. And you definitely can’t let it slow you down. Use it as inspiration or fuel for improvement, but remember that one voice is still just one voice.
