Have you ever heard someone say don’t let that become your sacred cow?  Before we start asking the question about what your sacred cow is we must first identify what a sacred cow really is?  If you look it up in the dictionary or google it will tell you that sacred cow is a noun and it means: an idea, custom, or institution held, especially unreasonable, to be above criticism.  So, if we try to understand this, I look at what this means I would say it is something we don’t like to question or something that we feel like we are not allowed to question, maybe even taboo to mention it.
