Synergize means working together to accomplish more and come up with better ideas than any individual could alone. The document provides an example of how a cheerleading team with 17 members can achieve more than a single cheerleader. It then outlines five steps to synergize: define the problem, understand others' ideas, share your own ideas, think of new creative solutions, and pick the best solution. An example problem presented is a student deciding whether to finish a science fair project or see a movie with friends, and potential solutions are discussed.
