What advantage is there to treating each implementation of a solution as a learning experience?

Although there are very definite advantages to solving certain problems as a group, others can be solved more effectively by an individual. It's important to know whenand when not to work in a group.

By treating each implementation of a solution as a learning experience, you are removing any sense of blame from the experience and allowing yourself to learn from the successes and mistakes of the solution. This will, in turn, allow you to build up your sense of what solutions will work to solve future problems, and even how to prevent future problems.
