There’s always room for improvement. As Musk explained, “It’s very important to have a feedback loop, where you’re constantly thinking about what you’ve done and how you could be doing it better. I think that’s the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.” Jason Bliss, founder of Healthy Living Network, says he lives by Musk’s advice. “Don’t be afraid of negative criticism,” he says. “It often reveals key insights you’d never discover on your own.”
