I remember reading a sutta where it listed reasons why a heedless person wouldn’t meditated, but a heedful person would.
For example, a monk is sick he thinks, "I am sick. I will wait to meditate until I am well. While a more diligent monk thinks, “I am sick, I may get sicker or not recover. I should meditate now”.
There were a few other examples, but they followed that same structure.
