There are more than enough sacred cows in this field to go around and if you’ve ever had to go up against one, you know how difficult it is to make headway. Pushback is usually swift and aggressive but that doesn’t mean you can’t think your way through the process.
Theoatmeal.com’s Matthew Inman published a wonderfully remarkable post on the sort of thinking that goes into sacred cows, or what people internalize as core beliefs.
If you aren’t already familiar with Inman’s work, know that it can be NSFW and this one is undeniably NSFW. If that’s a problem for you, Inman has you covered with a clean version.
I won’t spoil everything for you but be prepared to accept the responsibility of leading by example.
