There's few things that makes me dislike someone quicker than when they dismiss the suffering of others, or use their own circumstances to dismiss others inability to "just don't X".
Or trivializes other people's work. Like when a lead developer or a manager wants to chime in and say the story point estimate is too much and it should be smaller.
This is one of those things that someone pointed out to me, I agreed with them and have since tried to avoid saying "just do ...", "why not just ...", etc.
However, that means I now really notice it from others. sigh
I generally try to avoid the word just. However, I'll still occasionally use it during a code review, when I see a large amount of code that can be replaced by something much simpler and smaller.
An ex-coworker introduced the rule that every time someone said "You just..." he increased his estimation by 1 level (standard fibonacci planning poker).
That was like 15 years ago and I've at least mentioned that rule to every team I've been a part of ever since. It usually works.
Look, man, shut up.
