The current concept is somewhat specific. However, if we skip the preamble, it means a fairly simple idea:
When you go through difficulties and obstacles, treat yourself as if you were supporting a good friend in an unpleasant situation.
Our worldview is rooted in the habit of self-criticism. We are overly critical and intolerant of ourselves when we make mistakes. And it is ironic, because at the same time, when someone close is facing a problem, we show extreme compassion and support with words like "everything will be fine".
This problem goes back to childhood. From the time when we learned that the secret of success and happiness in life is strictness towards ourselves. Like a stern mentor who scolds young people for any reason.
Most people could work more effectively and with greater enthusiasm if they stopped blaming themselves for failures and mistakes.
Because when you blame yourself for a mistake, you only add stress and unpleasant emotions to the initial disappointment - you fuel the fire, in other words.
And to avoid these bursts of unpleasant emotional spirals, learn to practice self-approval. And not just practice it, but replace criticism with habitual self-compassion.
The result will not keep you waiting. And it will not only affect your specific actions, but also your moral and psychological attitude.
