There seems to be a recent meme around HN lately that you have to be a "hustler" to succeed. I think that's been misinterpreted a lot. Most of the hustle is in showing up, staying alert, and then applying just the right insight that will let your target know that your interests are their interests.
As recently as last summer, I felt that I had to make a lot of noise to make my ideas heard. I got nowhere. Instead, I've found that by listening to other people's ideas and then carefully suggesting ways to improve them, I end up with far more influence over how things actually turn out.
