These all worked for me. Read books and journals from parts of the library you are unfamiliar with. Get involved with a regularly meeting community of people who get shit done (hack space, programming language meet-up, radio station, life drawing, etc). Start a project that lets you interview the people you admire (blog, zine, podcast). Offer to work for a while in exchange for lunch in the coolest place you can think of. Install and ‘hello world’ as many tools as you can. Disassemble and rebuild something technical (like a phone or laptop) using instructions from the web. Watch classes on MIT OCW.
