Not a popular opinion, but a lot of product designers should just become artists (not a bad thing, btw)
Good product design is solving business needs in the most creative, effective, and elegant ways.
But there are many people that lose sight of that end goal, and get stuck on just trying to make things as flashy and novel as possible.
Visuals are extremely important, but they are the means to the end, not the end themselves. This paradigm is what has largely driving the Dribbble-ification of the industry in recent years.
I know there are going to be at least a few people who are reading this still and beginning to draft a reply about Steve Jobs / Apple / etc in their head...
I know. Apple has historically been known to create beautiful products, hardware, and interfaces. Jobs was known as one to put Designers and their ideas ahead of any other priority.
But what makes Apple design iconic, is that it gives people, their users, most of the world... purpose. They solve business goals (make personal computing available to the masses in a elegant way, let creatives do their best work, etc).
It is OK to create, just to invoke an emotional response from the audience, but product design isn't the best medium to do so.
Create something stunning, beautiful, and new. But give it purpose. Don't lose sight of the outcome of what you design. It's a balance, and finding the perfect blend of art and science is what makes product design fun.
I had the privilege to learn this balance from some of the best (thank you,

Go forth and make beautiful businesses.
