Stalking is an obession. Most stalkers work regular jobs and in their off time they stalk instead of hanging with friends, ballgames, the gym etc. They do not live the "normal" life that most of us are accustomed to. Stalking is the stalkers other life. Of course, stalking is free unless they get caught and go to jail. I categorize criminals into two basic types, organized and disorganized. An organized stalker will have pre-planned his/her event and be careful and cautious to not get caught or leave any evidence. Naturally, the disorganized stalker will be the complete opposite and operate from raw emotions, not pre-plan, leave eveidence and eventually get caught. However, after a while of committing crimes, even the most careful criminal will become overly confident and this is when they let their guard down and hopefully get caught before someone gets raped or murdered.
