where to go?

i'm having trouble with narrowing. my paper theses aren't narrow, my thoughts aren't either. this is troubling when confronted with the task of choosing. where should i go when i'm in europe? should i spend more time in berlin or concentrate on traveling?

in no particular order, (but in some particular order) here is where i'd like to go next semester:

istanbul, paris, rome, barcelona, prague, athens (plus every island in greece), st. petersburg and moscow, london (and to visit alex and laurence in their home towns, too), edinburgh, dublin, florence, venice, madrid, budapest, amsterdam, sarajevo, vienna.

there's more, but i already know the above is too much.

where do you go, when you want to go everywhere?
