| I can confirm. I co-wrote a book on "growth hacking" (https://secretsaucenow.com), which really serves as a hand-held, step-by-step guide to user acquisition. (I originally called it "user acquisition" but unfortunately "growth hacking" performed 4x better in A/B tests). It was really hard to do, but wow. Sometimes the self-promotional marketing feels kind of cheesy to me, but man, it's so worth it. First there's the cash. We've sold over $120,000 worth in the past 9 months, and did it direct without any publisher, so that's all straight into our pockets (after fees). I now have 2-3 people reaching out per week asking me if I can work for them, including big/successful YC companies. I'm turning all of those down, but I feel like if I ever needed a job again or wanted to go freelance I could do it 100x easier because of a book. I'm pretty proud of the book; I think the book is really good, and so far as I've found it's the only actionable Internet marketing guide out there. I put a ton of thought, effort, and energy into it. But I had no idea that a book could have such an effect in a day and age that's seemingly flooded with this kind of information. |
