The antonyms for the word "pleasureseeking" are words that describe the opposite of pleasure-seeking behavior. Some of these words include restraint, asceticism, self-control, self-denial, and self-restraint. These are all terms that describe a person who actively seeks to avoid or minimize pleasure in their lives, instead preferring a lifestyle that is more focused on discipline and self-improvement. For example, someone who practices asceticism might choose to live a frugal lifestyle, eating only what is necessary to survive and foregoing luxuries like alcohol or entertainment. While these choices may not be for everyone, they do represent a stark contrast to the hedonistic pursuit of pleasure that is often glorified in our modern society.
