"Flying is in your blood. You should be the sort who makes model planes, jumped off high things with home made wings (probably when younger and less wise!!) and will ALWAYS look up when you see or hear an aircraft. Just being near an airport should excite you and you change TV channels when something about aircraft or flying is on."
Personally I find these kind of people in aviation the most boring and irritating. Gimps with nothing else in their lives. You need to have more in your life than flying and if you spend your time making model planes then you need to get out of the house more.
Flying can be a fun and satisfying activity and a great way to make a living but there are plenty of things I find more exciting.
No captain is going to want to sit next to an FO whose only line of converastion revolves around flying.
