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.
"All we can do is our best. Sometimes the best that we can do is to start over."

"If you want him to think big, give him something big to think about."
"If you want to succeed, really succeed, the only choice you have is to mentally toughen up."
"Doing your best is the only option, even if it results in failure."
