Develop your designs quickly using sketches, wireframes or prototypes and share early and often. Share with your team and, even better, with the people you are designing for. Resist the temptation to dive straight in with a high fidelity design, that takes hours to make. Avoid giving your ego the time to think it’s right and that this design is “the one”. Listen carefully, accept critique, and be willing to be proven wrong by default. This will result in faster iterations towards a better design.
