In my opinion that is not a horse business, that is spending all day with your horse. The difference between having a business with horses and having horses as a hobby is that a business aims to run at a profit. Part of that process is monetizing your time and that should be a high priority for a new equine business owner.
Don’t get me wrong, once the business has been established there are benefits and spending more time with your horse could be one of those benefits.
However taking the benefits before you have put in the effort is like going through the finish pegs without doing the jumps.
You can’t be a winner if you haven’t put in the effort.
