I have polled more than 1100 people for their top three, and found the largest issues to be (percentages represent the percentage of people who indicated the issue): Ineffective or unsupportive leaders (26%) Difficult coworkers (25%) Stress and time constraints (21%) Since most people look for someone else to fix work issues for him or her, I decided to write this book to encourage you to take accountability for your happiness at work. Almost never will someone else take care of these things for you. You own your career. Make it something you enjoy."
