It might be that the attitude comes, not from actually thinking &quot;my stuff doesn&#x27;t matter at all&quot;, but more from thinking &quot;if I leave, almost anybody else could do my job&quot;.<p>Not sure if this was the case, but I believe a lot of our developer egos would like us to think that I and ONLY I would be able to do this particular thing (even if you know you&#x27;ll actually never be THE ONLY one at anything) it definitely feels like you might be one of the very few.<p>And then when you realize that no, you are not a special snowflake, you kind of feel &quot;my contribution doesn&#x27;t matter&quot;, not in that it doesn&#x27;t actually matter at all, but in that someone else could&#x27;ve done it as well.
