My wife and I work in similar fields. Years ago, during a casual conversation, she suggested an approach to a problem I was dealing with. I used it in a meeting, and my boss loved it.
When people praised me, I didn't mention her. That idea helped my career more than I expected. She knows I used it but doesn't know how much credit I received. Every time someone calls me innovative, part of me remembers a conversation at our kitchen table and feels like a fraud.
