Work with someone who thinks nothing like you. The friction is where the sparks come from.

Working with people who think like you feels smooth, and smooth means nothing gets tested. Someone with different instincts will question the thing you assumed, which is annoying in the moment and is exactly where the useful part comes from. Friction of that kind is not conflict. It is two sets of blind spots covering for each other.

Bring in one person whose taste you do not share for the next project. Agree at the start that disagreement is the point, so nobody takes it personally later. When they push back, ask one more question before defending anything.
