The author illustrates this with personal routines, such as walking while listening to audiobooks and coding regularly, to underscore the value of integrating habits into one's identity.

By fostering a mindset that embraces continuous, deliberate practice, the message encourages readers to fall in love with the process of personal and professional growth, making it an integral part of who they are.
