The opposite of changing ways could be described as a strict routine or an unchanging pattern. Words like "fixed," "unchanging," "steady," and "constant" all capture the idea of a consistent way of doing things. Additionally, the idea of "resistance to change" or being "set in one's ways" can serve as antonyms for changing ways. These terms imply a reluctance to alter habits or behaviors, which is the opposite of someone who is open to adapting and evolving over time. While there is value in both consistency and flexibility, understanding the opposite of changing ways can help us appreciate the benefits of each approach.
