Don't think in terms of comfort; think in terms of freedom. Don't think in terms of safety, think in terms of being more alive. And the only way to be more alive is to live dangerously, is to risk, is to go on an adventure. And the greatest adventure is not going to the moon - the greatest adventure is going to your own innermost core.
The freedom from something is not true freedom. The freedom to do anything you want to do is also not the freedom I am talking about. My vision of freedom is to be yourself.
