What kind of business is easier to manage for one person at the start?

Trying to figure out what makes more sense for a solo start. Service business, something online, maybe a niche local operation. The goal is not to build a giant company overnight, just something that can realistically be managed by one person without getting crushed in the first few months. Interested in examples from people who started lean and kept things under control.

Usually the easiest option is something simple, service-based, and low overhead, especially when one person handles sales and delivery alone. What matters is not what sounds impressive, but what can actually be run without chaos. That is where browsing organized idea categories on bizop can be useful, because it helps cut through scattered thinking and brings the focus back to manageable business models.
