In Chapter Seven of Malcolm X, Malcolm reflects on what it means to be a hustler. How does he describe the lifestyle?

From the text:

Fulltime hustlers never can relax to appraise what they are doing and where they are bound. As is the case in any jungle, the hustler's every waking hour is lived with both the practical and the subconscious knowledge that if he ever relaxes, if he ever slows down, the other hungry, restless foxes, ferrets, wolves, and vultures out there with him won't hesitate to make him their prey.
