Don't loaf and invite inspiration; light out after it with a club.

London rejects the romantic notion that writers (or artists generally) should wait passively for a muse. The blunt, physical image—“light out after it with a club”—casts inspiration as something to be pursued aggressively, even hunted down, through effort and discipline. The line aligns with London’s broader public persona as a strenuous worker and adventurer: creativity is not a delicate visitation but a product of will, routine, and persistence. Read this way, the quote functions as practical counsel about craft: show up, work, and force momentum, because inspiration is more likely to appear when you are already in motion.
