You Can Do It, Mello! is a section in Ryuk's Human Observation Journal. Ryuk, noting that Mello has gotten into a lot of fights throughout the series, ponders his success rate, and uses this section to calculate it for himself. He lists each of these confrontations as "rounds" and gives information on them, as well as his own input and Mello's (each time Mello comments his appearance varies to match how he looked at that point in the story).
