This quote is a reflection of Thoreau’s preference for the road less traveled, both literally and metaphorically. When he says, "Roads are made for horses and men of business," he is referring to the conventional paths that society often follows. These paths, like roads, are designed for efficiency and speed, for getting from one place to another as quickly as possible. This is the realm of business and practicality, where the journey itself is often overlooked in favor of the destination.

The second part of the quote, "I do not travel in them much," reveals Thoreau’s personal choice to diverge from these well-trodden paths. Instead, he opts for the wilderness, the untamed, the unexplored. This is a metaphor for his preference for original thought, for individuality, for the ability to think and live outside the confines of societal norms and expectations.

Applying this idea to today’s world or personal development, we could interpret it as a call to value our own unique journeys, rather than simply rushing towards prescribed goals or destinations. In a world that is increasingly fast-paced and goal-oriented, this quote reminds us of the importance of slowing down, of appreciating the journey, and of forging our own paths. It encourages us to value individuality and originality over conformity and efficiency.

In terms of personal development, this quote could inspire us to pursue our own interests and passions, rather than simply following the paths that society has laid out for us. It might mean choosing a career that we love, rather than one that is simply practical or lucrative. It might mean taking the time to explore and understand ourselves, rather than simply trying to fit into societal molds. Ultimately, it is a call to live authentically and thoughtfully, to appreciate the journey as much as the destination.
