Sales is a great field to be in especially if you have an entrepreneurial spirit, consider yourself a self starter, and are easily driven to beat or exceed your goals. When thinking about radio sales, always try to think big picture. The larger the sale, the larger your potential commission/income. So when I think about it, it's really advertising sales across all media. That could be selling ad space on the radio but also Pandora, Instagram, SnapChat, or Facebook. If I was to suggest one person to follow on Social Media, it might be Gary Vaynerchuk. His posts often offer great advice on work ethic and decision making early in your career.
