Tip of the day: If you have one of those days where it just doesn't feel right to be stuck inside an office, a classroom, your room or whatever other boring place for the whole day, do the following (read it all before you start):

a) Go to the city center
b) Hop on to some bars, cafes, art shops, trendy places
c) Grab those free postcards, one or two of each. They are free to take, grab at least 20, not all form the same place
d) Head to a sunny, well ventilated place. Preferably where you can sit down and write (e.g. beach, public garden, patio, esplanade, outdoor bar...)
e) Start writing to all of your friends from all over Europe
f) You should have probably brought a pen with you
g) And you should also have some way of getting their addresses from the internet... (Private Area, Facebook, Address book...) or just get them before leaving the boring place you're in (I'm sure that boring place has internet... all boring places do)
h) After you're done writing the postcards write STS where the Stamp should go
i) Enjoy the sunny day
j) Put the postcards into several different post boxes all through the city

that's it... wait a few days / week and we'll see who gets your postcard.

The advantages of this method are that it's free, you enjoy a sunny day outside instead of being stuck in an boring place, and you send a postcard to all of your friends, which is something I'm sure you keep thinking of doing, but never get around to actually doing...
