Great work requires being stubborn about your goals but flexible about your methods. The best people I know stick relentlessly to what they want to achieve, but quickly adapt how they'll achieve it when they see a better way. Most people do the opposite - they cling to their methods even when better options appear.
Elite rowers understand this balance instinctively: grip too tight and you'll catch an oar and flip; grip too loose and you'll lose control. The right grip isn't about strength - it's about knowing exactly when to hold firm and when to adjust.
Course correction is the beginning of infinity.
