To keep it simple you run your gym like you run your house. Keep it clean and in good running order. No jerks allowed, members pay on time and if they give you any crap, throw them out. There's peace where there's order.

为了保持简单，你可以像管理你的房子一样管理你的健身房。保持它的清洁和良好的运行秩序。不允许有混蛋，会员按时付款，如果他们给你任何垃圾，把他们扔出去。有秩序就有和平。
