Personally, my long term goal is to be able to speak smoothly, without pausing constantly to think about how to translate the next word or phrase. I'm okay with making mistakes and pausing once in a while to think, but not for every sentence.
I guess my short term goals are more activity-based. Right now I am reading a series, so my goal is to finish that series and then move onto the next one on my list. While I'm reading, I don't look up every single word I don't understand, because it's frustrating, it takes too long, and I don't retain the majority of the words I look up. Instead, I focus on the words that are important to know in order to understand the plot and the words that are repeated. Then, I upload summaries of every 5-10 chapters on the italki notebook, which I think is a really good way of practicing the new vocabulary that you pick up while reading the book. I also watch tv shows and listen to podcasts to practice listening.
I think its hard to measure progress, regardless of what level you're at. My goals are more aimed towards constant practice, which seems to work for me, and I definitely feel like reading books and writing summaries has vastly broadened my vocabulary.
