I have been a lurker for a long time - first on HTLAL and now here - and I think it's finally time to overcome my shyness become an active member of this awesome community.
I've been learning languages as a hobby with varying degrees of intensity for about 10 years now. I often beat myself up over the fact that my language learning efforts are so inconsistent and that I could already be so much farther if I didn't keep interrupting my studies for various reasons. But still, I've learned a lot and with a bit of luck keeping a log here and taking part in this community will keep me on the ball a bit better.
A brief overview of my language learning history:
English
I speak and understand English pretty much at native level (my pronounciation is not as good as I'd like it to be), having learned the language first at school and then through lots of reading, watching movies and talking to my friends (all of whom I've turned into English speakers, over the years >:D)
Japanese
Japanese was the first language I consciously picked up (English kind of happened on its own) and after a few years off off-again on-again learning I reached a pretty solid B2 level some time ago. I've mostly put the language on hold for a variety of reasons (I've lost interest in a lot of the things that drew me to the language in the first place, there's nothing I want to be able to do in the language nor things that I want to watch/read in it right now, I'd rather spend my time and energy on other languages, etc.)
I often despair (still!) that I didn't learn Japanese to the level I desired (C2, basically) and sometimes beat myself up over it, but I don't really regret my Japanese learning path. Besides the fact that B2 level Japanese skills are still pretty cool (I need to remind myself of that sometimes XD), learning Japanese taught me a lot about how I learn languages, how to self-study and how to make learning languages enjoyable. It made me find out about Anki and AJATT and Tadoku(!) and, of course, find HTLAL and set me down the path of polyglottery.
French
I originally learned French in school (more or less, anyway), then promptly forgot everything. It took me several tries to pick it back up, because it was more of a rational motivation ('It would be a shame not to capitalize on what I learned in school') than true passion for the language that made me want to (re-)learn it. I finally managed a couple of years ago (2011? I'm not quite sure), when my friend and I just low-key started watching Buffy in French once a week. We've been having French night once a week (nearly) every week ever since, having moved on to Angel, Arrow, Firefly and now Merlin after we finished Buffy. At times where I felt particularly motivated I supplemented this by reading some novels in French and watching other series or movies in the language. I also declared French to be my default video game language, though I'm thinking of changing that to another language soon (not that I play all that much anymore, but those 100s of hours I played Skyrim in French were certainly helpful!). All in all, I'd rate my level pretty much at B2, with my passive skills a bit higher and my active skills somewhat lower for lack of practice.
Latin
One of my main languages right now (together with Spanish). Learned it to that level where I could translate stuff more or less well a few years ago, then left it lying unattended for a while. Now I picked it back up with a friend of mine about 2.5 months ago and we've been reactivating our Latin by working through the excellent Lingua Latina Per Se Illustrata: Familia Romana.
Spanish
Knowing French (and some Latin) certainly makes learning Spanish feel like cheating. Besides a couple of levels on Duolingo at the beginning, I mostly learned by jumping right into watching TV shows and reading novels in Spanish. As such, my passive skills are not too bad (hard to judge accurately, but I could pretty comfortably read the first three books of Canción de hielo y fuego this year). My active skills, however, are basically non-existent - something which I hope to remedy next year.
Dutch
Dutch has been on my language wishlist for a long time (it's just such a cute language, it always makes me smile!), but it was never at the top of the list. I didn't mean to start learning Dutch right now - I was going to concentrate on my Latin and Spanish, but the wanderlust struck and I ended up starting the Duolingo Dutch course a little over a week ago. I'm quite enjoying it, so I thought to myself what the heck and decided to add it to my active languages. It'll be a low-priority language for a while at least and I've no idea where I'm going with it, but hey, gotta have a hobby. XD
Vague goals for the more-or-less near future:
*Improve my Latin to the point where I can read classical texts fluently without a dictionary.
*Reach a level of at least C1 in Spanish (both passive and active!)
*Learn some Dutch (told you it was vague
)Language wishlist (because there's too many languages and too little time):
*Ancient Greek
*Polish
*Chinese
*Italian
*Portuguese
*Esperanto
Inspired, among other things, by Elenia's log, I've decided set myself weekly language learning goals. This will give me something to aim for each week and give my learning some structure, without tempting me to set exceedingly ambitious goals, like long-term goals always do. Posting these goals and my results here will hopefully also make me feel more accountable. So, without further ado...
Weekly Goals for Week 51 (2015)
Latin
*Do Anki reviews every day
*Learn present subjunctive forms
*Read chapter 20 of Familia Romana
Spanish
*Finish reading Los juegos del hambre (Started reading the novel this weekend and am about half-way through right now, so that should be quite doable)
*Watch an episode of Grey's Anatomy (Started the series last week and watched 4 episodes so far)
Dutch
*Duolingo every day
*Watch an episode of MLP (I know, I know. I've never watched it, actually, but I thought it might be easy enough for me to follow along and it's on Netflix, so I figure it's worth a try.)
and always worrying to see someone taking their cues from me 
your goals look great, and fun too, which I think is the important thing. Good luck with them! Also, I like that you have a video game language! I haven't made it official, but most of the games I play are in German (which I think is at least a little bit because of Cavesa).
