"I work in a moderately-progressive workplace, and if I ever need to seek the input of a supervisor on a big issue/something that may come back to haunt me, I'll talk to them about it, and then send them an email saying what we decided. This makes it clear what the decisions was (and more importantly, how I interpret it) and provides documentation to both sides that the issue was discussed and a conclusion reached."
"When I know I am wrapping up a coding session, I'll often leave a few trivial things unfinished - so that when I sit back down again for the next session, I'll have an easy place to jump right back in, and it will force me to (consciously or otherwise) get back to somewhere near the mental state I was in when I half-finished the thing."
Are you really as important as you make out?
