What are some small business ideas that will allow me to deduct rent/internet/utilities from taxes?

I have a high-income job and live in an HCOL area where I pay $5000 in rent + utilities. I was watching Sherman's videos about reducing taxable income by having a small business and expensing rent and stuff.

Has anyone done something like that? Setup some business simple to expanse the majority of expenses and reduce taxable income? If so, I am open to ideas and suggestions where my apartment can have a legitimate 'business purpose' for rent as a business expense.
