My New Year's Resolution is to reach at least C1 in French by the end of the year :), or in other words, be able to follow a conversation amongst a group of francophones speaking to each other. I believe that New Years' Resolutions with a clear goal and endpoint are more effective than a vague one (e.g. "I want to improve my French"). I have been working on my French almost every day this year so far, so yes, to answer your question - I have stuck with my New Year's Resolution :)

I rarely make New Year's resolutions. As Yoda says in Star Wars, "Do, or do not--there is no 'try.'" I made exactly one New Year's resolution this year, though: I resolved that I was going to change my main account on my personal computer from being an administrator's account to being a standard account. I have done so.
