Just when the caterpillar thought the world was ending, he turned into a butterfly.
Think of your initial design concepts as caterpillars–rather clumsy, slow, vulnerable to a quick death, etc… But, if you let it continue to thrive with evolving iterations determined by your own somatic changes as well as outside feedback, this caterpillar of a design concept will incubate into a full-fledged viable design solution.
No idea is viable from its initial conception. It has to become viable through feedback from the real world. Designers should never design in a vacuum. Being part of a group to get feedback helps an idea become something beautiful.
Let the design process happen and let the world benefit from your butterflies.
