Between Unique and Flexible

As I consider, an attractive person should have his or her own taste, which means 'inclination'. Those who don't have any characteristics are boring. When I meet boring people, there is nothing to share because it is too hard to bring up a topic to talk about. It's a torture!
However those who have too strong taste is difficult to get along with as well. The kinds of people are likely to be sttuborn. They need the more flexible attitude. On the contium between two ends, it is tricky to find a moderate point to settle myself. Where am I?
