"I never saved anything for the swim back"
https://news.ycombinator.com/item?id=145582That's a quote from the movie Gattaca by the main character answering his genetically superior brother's question as to how he beat him in a swimming competition in the ocean.
I really like that quote, and thought it was appropriate at a time when YC apps are coming due. Jessica Livingston says in "Founders at Work" that the common trait between the founders was determination. Maybe the best example that I can remember is Evan Williams who went through a lot before Blogger was successful (losing friends and more).
What has struck you guys as the best modern-day example of determination (it need not have turned out successful)?
Another good one was the guy the movie "The Pursuit of Happyness" was based off of (though I'm not sure how accurate that story was)
