Rick Monro is a designer and writer from Belfast, N. Ireland and Head of Design at design and development agency Tibus. He writes on UI design (and other topics) at his personal blog, Designing the Middle. You can also follow him on Twitter.
Becoming an effective designer requires embracing universal design principles and best practices. Over the years, I have come to see that reaching maturity as a designer is a continual process of reassessment and letting go of potentially damaging baggage.
This can include jettisoning your ego and dumping your assumptions, prejudices and even your own opinions. There can be no sacred cows when you try to become what I call a selfless designer.
