Organize closets for people who can't organize their own closets.

$$: Middling, unless the closet belongs to some crazy rich person, and who else would hire a closet organizer?

The upside: Unparalleled opportunity for those with an unhealthy interest in footwear.

The downside: Hard to explain what you do to serious people, and therefore you may not find yourself around many.

The dark side: Obsessive-compulsive disorder acquired over time degenerates into horrible need to keep everything on matching hangers, followed shortly by madness and death.

Where you go from here: Stager, another bullshit job, where people set up an apartment that's for sale to look more attractive than it actually is.
