Paul Tudor Jones expressed the core of the trader’s work ethic in this year 2000 interview excerpt:

Q: What’s your competitive advantage as a trader?

A: The secret to being successful from a trading perspective is to have an indefatigable and an undying and unquenchable thirst for information and knowledge. Because I think there are certain situations where you can absolutely understand what motivates every buyer and seller and have a pretty good picture of what’s going to happen. And it just requires an enormous amount of grunt work and dedication to finding all possible bits of information.
