Good advice from Paul Graham: “Worry most about how to make something people want. If you’re building anything good enough to copy, you’re way ahead.” Side note, I found this post on FuzzyBlog at the end of a chain of hyperlinks. Interesting what we each picked out from the original post. I agree with Scott that implementation is critical, but I don’t agree that ideas are easy, at least not ideas that have been thought through to the point where you could actually build them. Making something people really want means getting outside of your own head, and that’s pretty hard for most of us. I’d riff on Paul’s post by saying that mastery of implementation — stuff like identifying the substrates on which to build, scoping, dependencies and schedule — is sort of like getting a black belt in karate. It’s an achievement in one sense, but more significantly, it’s a gateway to greater things.
