WordPress is like a chest of drawers: you just have to learn where everything goes.
This is one of the first things I tell bloggers in my WordPress Workshop. I say, you will save countless hours and gray hairs by memorizing all the nooks and crannies of the WordPress Dashboard from the get go. WordPress may be user friendly, but it is also a labyrinth, so brain map it.
Think of the Dashboard Navigation as a giant chests of drawers, with more drawers nested inside of each drawer. Users simply have to remember which drawer to open to find the page where the data belongs, to put everything in its proper field.
