 1. We have to keep track of the lights to make sure all directions are illuminated.
 2. Lights are expensive, and we want to add as few lights as possible to our scenes.
 
-Adding more and more direct lights to your scene will quickly kill you framerate, so direct lights alone are rarely the best choice.

 Try experimenting with different values for `widthSegments` and `heightSegments` to see how these settings affect the quality of the geometry. It's important to use the smallest value that looks good for both settings. The number of triangles the sphere is built from increases very quickly when you use larger values for these parameters. What you're looking for is a tradeoff between quality and performance. If the sphere is far away from the camera or very small, you might be able to get away with a low-quality geometry made out of very few triangles, while if the sphere is the main focal point of your scene (such as a globe or planet), you will probably want to use a higher quality geometry.
