I have made a point to start and finish on time, along with taking my lunch breaks and regular hourly little stretch-eyesight breaks..
It's all the time in between that I struggle not to go 100%, burn out, and start making stupid mistakes.
The last few weeks have been a thorough burn out, and we're only in February.
The good thing in our team is they send the draft back to people who know the role for review before posting.
