I know what things are good: friendship and work and conversation. These I shall have.

The speaker pares “the good” down to a small, human scale: companionship, purposeful activity, and the exchange of ideas. The triad rejects grand abstractions (fame, wealth, heroic destiny) in favor of what sustains an inner life and a community. The final sentence—“These I shall have”—adds resolve: goodness is not merely recognized but claimed, as if it can be secured by choice and attention. Read in light of Brooke’s reputation for idealism, the line can sound like a self-prescription against restlessness or disillusionment: when larger meanings feel unstable, one can still commit to the durable goods of friendship, work, and talk.
