But there's no such thing as instruction buttons. It's not like software is a physical thing where you can't easily change where buttons point to. What makes more sense to your mom: that the huge button labeled "Create a new list" teleports the user to the "Create a new list"-page, or that it shows the user where to actually click to start the confusing road towards the "Create a new list"-page?

You say normal people don't mind clicking. I say you don't have much experience with normal people. Any time you add an extra step in your funnel, you'll have a higher drop rate.
