Controlling liability with sole proprietorship?

[Tanner Johnson]

I am operating as a sole proprietor at 22 years old with 22 units grossing about 160000 netting about 80000 and needing to know what the best route is to protect myself, currently have some liability insurance but I want to know what others do, especially with quite a few units under a sole proprietor, to control their liability. Thanks

Reality is liability/umbrella policy is sufficient. Personally, I have several LLCs and some thru a trust that is managed by an LLC as I prefer to remain as anonymous as possible as I don't like people to be able to easily find out what I own
