Remain neutral to start. You can always add, but once form is established, it is hard to change. Forming out of neutrality, slowly over time, allows for evolution.
We are not rigid. We can admit wrongs and learn to become better. Better at relating our designs to their intended recipients, better at empathy, better at everything.
The recipient of our designs should also form their story into the design. If our design has too much personality there is no room for others. That’s just plain rude.
