Work life today is hectic, to an extent that might have been hard to imagine just a generation ago. Stress levels are through the roof, and many workers struggle to stay engaged, let alone productive. 

Author, lecturer and motivation coach Andy Core addresses these issues in his new book, "Change Your Day, Not Your Life," offering advice on how to move from "striver" to "thriver."

"To start reclaiming the goals that once inspired and excited you, you'll have to change the way you approach your day," he says. "Instead of a worker whose actions are dictated by supervisors and to-do lists, you'll need to begin acting like the CEO of your own life."
