"Not only don't I know who I am, but I'm very suspicious of people who do know who they are. I am sometimes ten or twelve people a day, and sometimes four or five people an hour!"

In this quote, Tom Baker reveals his uncertainty about his own identity and his apprehension towards those who declare to have a clear understanding of who they are. He suggests that he is constantly altering and progressing, taking on different personas throughout the day. This could be analyzed as a reflection of the complexity of humanity and the idea that we are not defined by a single identity, but rather a mix of various characteristics and attributes. Baker's words likewise mean the idea that understanding oneself totally is a difficult and possibly impossible task, as we are continuously growing and adapting to brand-new experiences and situations.
