I recently watched this short talk from Sarah Knight:
While I was watching the video I got in touch with someone saying no to something they’d asked me to do. I knew that was what I had to do even before I watched the video. In the video Knight says that we need to say no to things we don’t care about. I don’t think I have trouble with that. I find that often I do need to say no to things even though I care about them, because the folks who want me to be involved aren’t treating me well. (To reuse Knight’s language, they don’t give a fuck!) I need to remind myself that it’s not worth working with people who are going to treat me badly, even if the cause is good.
