I prefer design by experts - by people who know what they are doing

And to get real work experience, you need a job, and most jobs will require you to have had either real work experience or a graduate degree.

The designer shouldn't think of a simple dichotomy between errors and correct behavior; rather, the entire interaction should be treated as a cooperative endeavor between person and machine, one in which misconceptions can arise on either side.

In the university, professors make up artificial problems. In the real world, the problems do not come in nice, neat packages. They have to be discovered.

Everything has a personality: everything sends an emotional signal. Even where this was not the intention of the designer, the people who view the website infer personalities and experience emotions. Bad websites have horrible personalities and instill horrid emotional states in their users, usually unwittingly. We need to design things-products, websites, services-to convey whatever personality and emotions are desired.

The world is complex, and so too must be the activities that we perform. But that doesn't mean that we must live in continual frustration. No. The whole point of human-centered design is to tame complexity, to turn what would appear to be a complicated tool into one that fits the task, that is understandable, usable, enjoyable.

Behavioral design is all about feeling in control. Includes: usability, understanding, but also the feel.
