Jonathan Ive

When you're trying to solve a problem on a new product type, you become completely focused on problems that seem a number of steps removed from the main product. That problem solving can appear a little abstract, and it is easy to lose sight of the product.

Personally, I like to juice up several different kinds of fruit and vegetables - which may include various combinations of bananas, red bell peppers, apples, carrots, celery, broccoli, spinach, parsley, tomatoes, cucumbers, etc.
