Change this... Now this...

Sometimes in the design world, you could be working on a project for hours on hours. And then at the very end you find out that the change is minute compared to how long you spent changing the design over and over again. Working with customers in the real world can sometimes be easy. They will know what they want changed and you can change it in a reasonable time to the expectations that are asked. But other times the customer might not know what they are looking for and there for a design could change 15-20 times before an agreement has been made.
