It canīt be fun. Of corse you are the king of the world if you are a pilot on the 747 at the age of 21. But to me it sounds like you miss something. I would rather get the experience of the smaller planes and work my way up. Its nice to be 65 and have flewn everything from the c172 to the 747 I think. So if KLM called me tomorrow and said that I could start on the 737 or the 747. I would take the 737.
Cheers
