I must say, being at a good college like Hillsdale (or Bethany) really helps with the pressure thing. Having spent a summer block at Colorado College, a semester at Lake Forest College, and various short ocassions at state colleges, I can tell you (and anyone else who stumbles across this), that you may find yourself under much heavier pressure places like that.
Sounds like great advice, I'll try to remember it in three years.
How much does one organize Calvinball?
One simply prints up posters telling everybody that a game of Calvinball will be played at a certain location at a certain time on a certain day. One usually includes a relevant Calvin & Hobbes strip that explains the rules of the game, and then plasters said posters around campus.
