Thanks all, for the feedback! These are the kind of suggestions I was hoping for to put my own thoughts into perspective.
Different people have quite significantly differing opinions about what is adventurous or not.
For some, flying to an airfield they haven't been to before is adventurous. For others, flying a single engined aircraft over the North Atlantic to America would be considered adventurous!
Indeed and even to the same person, different things will be adventurous at different stages in their flying. For me, once I have received the license, the first time exercising the privileges granted will be a great adventure. This summer, flying to unknown airfields in the vicinity will be an adventure. Crossing the channel - as mundane as it might actually be - will be another adventure altogether, though even that will eventually not be enough anymore.
In fact, I think the key to a fulfilling flying life is to constantly find new challenges, not let yourself be succumbed into the temptations of the comfort zone and eventually become lethargic...
Cheers
Patrick
