You can always find a way to get into a business by either volunteering, or internship, showing interest in that field. Seasonal work allows the employer to see your work ethic, motivation, and performance. Sometimes it may take a few seasons to get there, like UPS, but once you prove yourself and show them what you have to offer, then its just a waiting game for a full time position to open up for you. You also may have to meet an age requirement, but in the meantime you will get a better idea of what they do, and how they want you to perform. Good luck!
