Thoughts on do good design

After i read the book, i had a of thoughts coming out of my mind. As designers, what are we looking for? Why are we designing stuff? Who are we designing for? To start learning to do good design, we need to understand different aspects of world's design and transform them into a creative way. We need to consider the market economy. How to affect people by things we design. We can't only design for economic use, If we design for good then we are helping aid design to be more useful and not just creating good design.
