It's funny. "Starting a farm" seems like it'd be easier than my current schlep, which is figuring out how to market an app. Researching "how to start a farm" seems like a problem I could sink my teeth into a lot easier. To me that supports your thesis.
I know you use it as a general example, but do some very basic research on what it would take to start a farm... and not go broke within a year. You will feel differently.
