Are holidays a luxury in business?

When I set up my first business, my business partner insisted we both take quite a bit of time off from the start.
 
Initially I thought this was an indulgence because being at the coalface is where you dig out the coal, right?
 
Boy, was I wrong and the holiday framework he insisted on, I ran for years and still do in a way.
 
Bottom line here, holidays are a business necessity, not a business luxury.
