Walking away from problems he doesn't want to face. He thinks about life and worries, is he his too literal. Friends he doesn't have. Girlfriend that doesn't exist. These things make him over-think. He wants an education but it's just a want. He wants a spouse, it's a want. He can't decide wants and needs. He needs a job but he can't decide what kind of jobs will accept and deny him, which will be entertaining but also won't need a high education to get in.
Walking along, deciding, and cannot find the perfect job other than some car job which will also require some knowledge. Thinking and walking, doesn't know where but he walks.
