"Hug the shore; let others try the deep"

This quote by Virgil suggests that it is smart to remain close to the familiar or the known courses in life, rather than venturing too far from them. The concept is that while some may be lured to explore the unidentified or take dangers, there is more security and security in staying near what is currently known and comfortable. By hugging the coast, one can avoid the threats and unpredictabilities that include venturing into deep waters, both metaphorically and literally. Essentially, this quote acts as a suggestion to exercise caution and make sensible options in life, instead of constantly looking for the unidentified.
