Ask HN: so many language options my head is spinning...

Here's another "new developer" question for you guys, but it's a bit different.

I've only been coding for the last year (in an arcane language called FAME) and I've enjoyed the creative side of my 9-5 so much I've decided to pick up more languages and CS basics, and maybe look for work in the Bay Area.

I've got a ton of ideas floating around in my head. Visualization/graphics/UX stuff on iOS. A web app for data analytics (something similar to chart.io). Toying around with a mobile OS (maybe messing with Android) some day.

I've picked up the basics of Python, and I've got a copy of K&R sitting next to me, but focusing on just one language is hard!

For those who started with no CS background and tons of abstract ideas: how did you decide what to learn and ship first? What languages would keep my options open to all these different ideas (web and mobile and systems)? Am I thinking too big here?
