I didn't like #9 either. It advocates putting yourself out there by pursuing the random possibility of an opportunity instead of opportunities that exist.
I agree you should have a plan. I think it's important not to avoid doing things outside of your comfort zone because you may miss a lot of opportunities that you couldn't have planned for.
Let me rephrase. Indirectly, possibly communicating with people you think can help you - like commenting on AVC's blog - and hoping they contact you is not going to be anywhere near as helpful as contacting them directly. It's not serendipity when you put out bait and hope it catches something.
