Fighting to get my estimates accepted. I try as often as possible to give good estimates. This seems to always mean mine are a little longer as I don't give optimistic timelines. I get pushed back to shorten timelines and I'll sit on my head refusing to do so. This is almost always when it comes to dealing with obscure bugs. It's very difficult to give a timeline for those, so after digging around and trying to find the root of the problem (or at least a general direction) I give an estimate of a few days (3-5, sometimes 7) for that. Fighting to have these estimates accepted is painful. It's especially annoying because one is made to feel like long estimates are an indication of slacking off. Everywhere I've been it's the same thing. It feels like a bargaining exercise at your local street bazaar. Not fun. Also, mildly demotivating for a short period of time.
