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.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
