"If you want to be really good at something, it's going to involve relentlessly pushing past your comfort zone, along with frustration, struggle, setbacks and failures. That's true as long as you want to continue to improve, or even maintain a high level of excellence. The reward is that being really good at something you've earned through your own hard work can be immensely satisfying."
