There will always be naysayers and people who want you to change something. If someone tells us that they don’t like something we do, something we sell, or something we make, we want to change it because we want to be liked.
It’s cliche, but true: The squeaky wheel gets the grease.
If you decide to change, that’s okay. Just be aware that the next person might not like the very change you just made to satisfy someone else.
On the other hand, it’s also okay not to change. If what they don’t like is a core element of who you are or what your product is, the person complaining might not be the right person for you or your offerings. When a change requires a lot of effort or impacts your sense of self or purpose, think long and hard before doing it.
