Identify the one goal which will benefit you the most in the long run, and stick with that one goal.  Think long and hard about which goal will really offer the most benefits.  If, along the way, you can find time to work on other goals at the same time, that's even better.  But if you try to do way too many things, or if you sit back and do little, either way you'll get nowhere in the long run.  

Unfortunately money makes the world go round... having a good education usually contributes to (but doesn't guarantee) a reasonable job afterwards, which then brings about other opportunities along the way, which you simply can't foresee now.  Learning a language is good fun and seems like a good use of time in the short term....  but in the long term would you be able to survive and have a good life that way?  (Hypothetical question, you don't need to tell me the answers, just think to yourself)

The thing is, you are probably trying to plan out your whole life right now, but "life is full of surprises" as the saying goes.  You simply can't know what you'll be doing in 4 years time.  In my eyes, the path which offers a lot of variability & potential opportunities & most security.... and the path which tends to help you figure out your life.... is quite often the education -> work path.   Just my opinion anyway. 

Having said all that though, I have some friends that have spent the whole time working in odd jobs & travelling the world and they've had heaps of fun for 10 years.  Who knows if they will ever "settle down" or "get a real job".  Ok now I feel conflicted, I'm probably not helping you at all haha :)

Ultimately you are the master of your own life, so all the decisions are yours to make.  But you cannot know everything that is going to happen.  Be prepared for the path to twist and turn along the way.  Make your life interesting and fullfilling along the way.  Just give yourself a bit of security.
