Laziness refers to a lack of motivation or unwillingness to exert effort in completing tasks. It is often associated with being idle, lethargic and disinclined towards work. People who are lazy may procrastinate, avoid responsibilities, and put off important duties until the last minute. Laziness can be a result of various factors such as lack of interest, low self-discipline or motivation, or simply an unwillingness to expend energy on something that is perceived as unimportant or tedious.
