Achievement is a personal thing. What brings one person a feeling of success has little meaning to someone else. However, every achievement involves three things - a sense of purpose, the capabilities to pursue that purpose, and the resilience to continue when the going inevitably gets tough.
Here are a diversity of movie quotes about achievement.
