Both "celebrity" role models and "people around you" works for me. They all have their positives and negatives and try to learn from them.
People around me are those that I know personally, which I can learn a lot from and seek advice.
Celebrity models on the other hand, have attained a certain level of success that most people around us have not and you should find something they have done correctly than can help you in your journey.
I see myself using both to help me become more successful.
