Jeff Lawson — Designing intuitive APIs is hard, but my recommendation is to make sure your API makes sense as a user of your system, not the designer of the system. Design the API first. Many API developers release an API that’s based on their internal models. But you may suffer from the curse of knowledge
Daniel Brusilovsky — One of the biggest pieces of advice that I took away from being an entrepreneur, especially a young one, is to never let people discourage you from your idea, even if they don’t believe in you. If you believe in your idea enough to risk it all, then you’re ready to go for it all.
Pete Barry — Great ads (and products) start with a great idea. So always think first, and design later. Start with literal, obvious ideas and then say the same thing in different ways. The more ideas you generate, the more likely you’ll come up with a great one; a promise that rings true with the consumer
Adam Cooke — Don’t overcomplicate your ideas from the start. Keep things simple and don’t try to do everything at once. When your project has some users, you can ask them what else they want and add it then. The most valuable thing you can have is a usable product.
