"In my opinion, he only may be truly said to live and enjoy his being who is engaged in some laudable pursuit, and acquires a name by some illustrious action, or useful art"

This quote by Sallust talks to the concept that a person can only genuinely live and enjoy their life if they are actively engaged in something that is useful to society. This could be an illustrious action, such as a heroic deed, or a helpful art, such as a craft or trade. Sallust is recommending that an individual should strive to go far on their own by doing something that is advantageous to society. This might be through a profession, a hobby, or a volunteer activity. By doing something that is helpful to society, a person can genuinely live and enjoy their life. This quote motivates individuals to pursue something greater than themselves and to make a positive impact on the world. It is a reminder that life is more than simply existing, however rather it has to do with making a distinction and leaving a lasting legacy.
