Designing Your Work Life is a book by Bill Burnett and Dave Evans that focuses on the importance of autonomy, relatedness, and competence in making one's job feel challenging and fun. According to self-determination theory, humans are intrinsically motivated animals with innate psychological needs for these three elements, which can be satisfied through work experiences. The authors argue that financial rewards alone do not motivate people as much as previously thought, and instead, human beings have an inherent tendency to seek out novelty, challenges, and exploration. They also emphasize the importance of autonomy, relatedness, and competence in job satisfaction and productivity. Managers are encouraged to design opportunities for their employees to experience these elements, which can lead to increased happiness, job retention, and success. The book suggests that passion may not be the starting point for one's career, but rather an emergent quality that develops over time through hard work and exploration. By satisfying autonomy, relatedness, and competence, individuals can develop their intrinsic motivation system and do their best work, feel more connected to colleagues, and experience a sense of meaning in their job.
