We are not all capable of everything.

Attributed to Virgil, this maxim expresses a sober recognition of human limitation: talents and aptitudes are unevenly distributed, and no single person can excel at every task. Read in a classical ethical key, it counsels self-knowledge and appropriate choice—directing one’s efforts toward what one is fitted to do rather than chasing universal mastery. It can also be taken as a social observation: communities function because different people contribute different strengths, making specialization and cooperation natural responses to individual limits. As a piece of practical wisdom, the line tempers ambition with realism and encourages humility toward others’ capacities as well as one’s own.
