Differences between “Approach,” "Perspective," and “Paradigm”
"Approach" implies a hands-on style. "Perspective" is more theoretical. "Paradigm" is similar to perspective, but implies that some specific model will be used, i.e., it will be a "systematic" perspective.
- What's your approach to saving money? (How do you do it?)
- What's your perspective on saving money? (How do you look at it?)
- What's your money saving paradigm? (What's the actual model?)
Sometimes these three terms are used interchangeably.
