my first job was at mc Ds when i was 15 its not a glory job but you need to start somewhere. every ladder has that first step before your at the top lol but another job ive had (HA had, i still do in on the weekends lol) is a farm hand do anything from raking hay to changing oil on the work trucks or mow the lawn lol if your near a farm id say pull in and just very nicely ask if they need any help. its hard work at times but it will get you in shape (nice if you play sports)

good luck man!!
