Role modeling is big for me. There are many people who can talk so well but it means little when it hasn't been tested and put in practice. So when I see an exceptional example in the wild, I tend to gravitate toward that person and learn from him or her. In essence, I will ask myself "What would he or she do?" in many matters I encounter.
In my case, he was an executive I worked for many many years ago. I am still friends with him long after he retired. If I were to act like him, I know I can do no wrong and so I will pretend I am him in demeanor and attitude.
Therefore, if there is a person you know personally (I advise against celebrities you don't know because the picture they paint might not be reality), you can do something similar. When you encounter a challenging situation, imagine you are him or her and suddenly you will know what to do.
