To be free from ego is to ensure lifelong learning.
When someone corrects us, or when something happens that reflects our mistake, we tend to get defensive. This actually is a form of ego, which deprives of learning. At least to you, we need to be honest and see what we can learn from it. This helps us to enrich us and progress constantly.
Today if think of one incident where things went wrong. You will then see what to learn from it. Even if 99% of it is another person's mistake, not think of that right now, but be focused only on what can we learn from it. Ensure to repeat this exercise for any other incidents that happen today. See the result which you have never dreamed off yet.
