David Bohm (1917-1992), a renowned physicist and theorist, was one of the most original thinkers of the twentieth century. He felt strongly that true originality and creativity were not the result of following a pattern, technique, or method, but rather the individual.
Frameworks and processes are useful to help people understand problems, but they don't make one inherently more original or creative. They help people see associations and connections between disparate elements, but it takes a person to make the actual connection.
Don't limit yourself by working strictly within a framework.
