I don’t pull punches with people I respect. It’s better that you know how you can improve than to leave it lingering in the background like some sort of stench you can’t smell. Unless, of course, I know you’re particularly sensitive to the idea of any constructive criticism, in which case I’ll politely guide you. These sprites of the main characters of An Insurmountable Odd wouldn’t exist if not for honest feedback. Don’t fear criticism.
“A lack of planning on your part does not constitute an emergency on my part.” I saw that on a sign on the first day of my first job, and though I’ve accidentally excused myself and others from that rule, it’s overall been my career’s guiding principle. Tasks take time. For last minute work, I will do the work “to the best of my ability” within the time available, and will strongly guide future timeframes.
