Whenever I speak, I try to convey one simple idea: don’t sweat the small stuff. Stressing over tiny mistakes you can’t undo is one of the fastest ways to drain your energy, scatter your focus, and invite self-doubt. Whether you’re launching rockets, running a team, or just navigating everyday life, the same rule applies. Ask yourself 'Can I fix this now?' If the answer is no, acknowledge it, extract the lesson, and move on.
