The only advise I can give is, if you go the autodidact route, learn the stuff that you don't like as well. Look up an official curriculum and pick at random. I've been to uni, and I think the major contribution it brings is forcing you the fundamentals of subjects you'd otherwise skip.

I hated compiler construction with passion. But I love that language design is now at least comprehensible for me when looking at new languages.

Of course this is just one example, another being formal methods/ software validation awesome stuff; would have never learnt it otherwise.
