“I will direct one day, but I have a feeling that it will be very limited.”
— John Travolta
Simplified Meaning:
The person is saying that they want to become a director in the future, but they believe their directing style or the kind of movies they make will be quite specific and not cover a wide range of topics. Imagine a chef who dreams of opening their own restaurant. They might say they want to do this one day, but they expect the menu to only feature a few dishes they are really passionate about, rather than a wide variety of cuisines. This chef prefers to specialize in what they love rather than trying to please everyone. The advice here is to know your limits and interests and focus on what you feel most confident and excited about. For anyone, it means understanding what you're best at and putting your energy into that specific area, instead of spreading yourself too thin. It also encourages embracing your unique strengths even if they are narrow in scope.
