Shading confusion

Hi, I'm trying to properly shade a sprite for my game. I have read some pixel art tutorials and I have become well aware of "Pillow shading" as something not to do, so I am in a bit of a deadlock here; The sprites in my game are supposed to be lit from directly above. How do I shade sprites from directly above without making them look ugly and unprofessional?
