One of my favourites is "Point At". It works great for point lights that are so small you can't find them in the scene.   And it's great for making eyes look at something.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
