Old men sometimes say to "do what you love". I don't think that they really mean to give yourself permission to go crazy. What it means to "love what you do".
The flashy and fancy sounding jobs usually come at a high personal price. Most people have many sides interests and abilities to them. Aviation is usually just one facet. People do not become accountants because they dreamed about it as a kid. They do it because they are good at it and it usually pays well.
It is better to love what you do and to choose a career that will love you back as well.
