You must learn day by day, year by year to broaden your horizon. The more things you love, the more you are interested in, the more you enjoy, the more you are indignant about, the more you have left when anything happens.

Barrymore’s advice frames emotional and intellectual range as a kind of resilience. By deliberately widening one’s “horizon” over time—cultivating many loves, interests, pleasures, and even principled indignations—a person builds a diversified inner life that can absorb shocks. The line suggests that loss or misfortune is less annihilating when identity and meaning are not concentrated in a single attachment or role. It also treats indignation as valuable: caring enough to be angered by injustice is part of being fully alive. Overall, the quote champions curiosity, engagement, and moral feeling as safeguards against the narrowing effects of hardship and age.
