There are other good answers, but I want to emphasize that a 1:1 is where you most definitely should blow your own trumpet. You may have done something great or important and your boss may not have noticed. Make sure they do so that it (hopefully) comes up when it's time to consider your raise. Also, though hopefully not often, that thing you think was so wonderful was not received that way. If that's the case, it's good to know soon so you can deal with the consequences (fix if needed, or at least learn that things like X aren't received well after all).
