Language such as &quot;exactly zero&quot;, &quot;dork around&quot;, &quot;mess around&quot; sounds aggressive, as if people who decide to hack on their tools were beneath you. When you say &quot;utter waste of time&quot; on people who do enjoy working on their vimrc or init.el or whatever, it sounds like you think the person themself is a waste of a person. When you mention how many years you have, you sound pompous, as if you were stating your opinions as facts (years of experience can&#x27;t be wrong!).<p>It sounds aggressive even if you don&#x27;t intend it to sound that way. There are ways to other ways to express your opinion without sounding this way.<p>Here, let me try to show you what I mean:<p>&quot;I am not interested in modifying my tools. I would rather pay someone else to do it. If you are spending time modifying your tools, then that is time that could have been better spent on another task. I have many years of experience, which have convinced me that the right way to spend your time is on your product, not your tools.&quot;<p>Note the lack of dismissive language such as &quot;absolutely zero&quot; or &quot;exactly zero&quot; or &quot;waste of time&quot; or &quot;I am simply&quot; (this last one is another attempt to present opinions as facts).
