Specialize on something relatively new and easy. You can then reach the frontier quickly. You saw this happen you Ruby back when Rails came out and you still see this happening with lots of HTML5 related technology, where what people think is exciting is really just somebody reading the specs and doing a basic hack.

I suspect that if you were to just focus on mastering Javascript, the DOM, SVG, and the various HTML5 APIs by really reading the entire spec, and pushing the boundaries of what is possible you could become better than most programmers in this domain. This is because most programmers that have been working for the last 10-20 years are not doing Javascript development, or when they do, they don't take it seriously enough to actually read the specs and push any boundaries.

Of course you will still be completely illiterate in many ways, but given six months that's just the reality. Maybe spend the final two weeks doing a quick survey of other tech, just so you aren't completely clueless.
