One major observation is how frequently design is described as a solitary activity, taking place mostly in one person's mind. Despite how rarely that happens in life.
Which makes for a professional trap: the major challenge of design (collaboration/persuasion) isn't seen as part of design education.
But I'm here to say YES IT IS. What good is a design plan if it can't be built? Or the team won't build it? A design can't change the world if it doesn't get made.
They polish ideas that designers likely already know, instead of poking at the corners where the real growth will be.
But it's a weakness to make this a specialization - the seeds should be planted deep and early in design education.
Theory: the world is badly designed mostly because of things designers feel aren't part of "design" (is this crazy?)
