From a 1997 interview between Dan Pink and Richard Bolles of What Color Is Your Parachute? fame:
Pink: Despite all the things we've discussed so far, you're not totally sold on the idea that the world of work is awash in change, are you?
Bolles: No, I'm not. There is a basic truth about what a human needs in order to survive; our culture seems unable to understand that. Human nature survives and has survived through the ages by being able to hold on tenaciously to two concepts: What is there about my life or world that has remained constant? and What is there about my life or world that has changed or is changing? I have always argued that change becomes stressful or overwhelming only when you've lost any sense of the constancy in your life. You need firm ground to stand on. From there, you can deal with that change. Observing the constants in your life gives you that firm ground. The thing about the great faiths is that they talk about what's constant in the world: God, grace, prayer. But our culture, in general — and the profession of career counseling, in particular — gets absorbed with a single question: What's changing? Nobody remembers to ask the other question, What's remained constant?
