Psychologist Heidi Grant Halvorson defines self-compassion:
"Self-compassion is a willingness to look at your own mistakes and shortcomings with kindness and understanding—it's embracing the fact that to err is indeed human. When you are self-compassionate in the face of difficulty, you neither judge yourself harshly, nor feel the need to defensively focus on all your awesome qualities to protect your ego. It's not surprising that self-compassion leads, as many studies show, to higher levels of personal well-being, optimism and happiness, and to less anxiety and depression.
"But what about performance? Self-compassion may feel good, but aren't the people who are harder on themselves, who are driven to always be the best, the ones who are ultimately more likely to succeed?
To answer that, it's important to understand what self-compassion is not. While the spirit of self-compassion is to some degree captured in expressions like "give yourself a break" and "cut yourself some slack," it is decidedly not the same thing as taking yourself off the hook or lowering the bar. You can be self-compassionate while still accepting responsibility for your performance. And you can be self-compassionate while striving for the most challenging goals—the difference lies not in where you want to end up, but in how you think about the ups and downs of your journey. As a matter of fact, if you are self-compassionate, new research suggests you are more likely to actually arrive at your destination." (read her whole article)
