What is the most profitable farm to start?

I'm curious, when it comes to starting a farm, what type of operation is considered the most profitable? Is it based on the type of crops grown, the livestock raised, or perhaps a combination of both? Are there any specific factors I should consider, such as the location, climate, or availability of resources, that could influence the profitability of a farm? Additionally, what strategies or practices can I implement to ensure my farm is operating at its most profitable level?
