solution sales, be it in IT, AV, Security, office equipment... Generally you work with different clients, in different parts of an industry or multiple industries. All have similar needs but various differences in applications that requires jumping into their work understanding why they need some things in special ways, and then jumping back out to move on to the next project.
Its lets you leverage your hyper-focus and quick study skills, but wont require you to master an particular thing. Its also often not a direct sales job, but a 1/2 tech 1/2 sales job where you support a traditional sales organization but are expected to be a technical jack of all things within your company/role/industry/product line.
