Table 1:  Basic interests:  roll your 1D6 (that means one six-sided die) and go to the number on the chart that corresponds with the number on the top of the die.  Then follow the instructions on which table to consult next.  Do it!
1:  obsession with some person or group.  go to table 1a
2:  knowledge buff on a particular topic.  go to table 3a
3:  you collect stuff.  go to table 3b
4:  you like to read stuff.  go to table 3c
5:  you like to do an activity.  go to table 4a
6:  you masturbate.  just kidding!  re-roll for Table 1 and try again.
 
 

P.S.  You may have noticed that my tables are not even attempting to be comprehensive, and some (many) of the suggestions aren't very helpful.  Frankly,  I did the whole thing in haste, so I could get back to my primary hobby, masturbation.  Mental masturbation, that is.  (Suuuuuure.)
