We think that failure shouldn't happen and that if it does, it means that something has gone wrong. But failure is not the opposite of success. It's the path to success.
We do not achieve success when we put sufficient distance between ourselves and our failures. We achieve success when we learn to bring our failures close, examine them with clear-eyed compassion, learn what we can from them, and use them as fuel for future growth.
Don’t fear failure! When a scientist does an experiment, he or she must be open to any result. Some results are good/positive and some are bad/negative but they are all useful data points.
The correct response to failure is to try again. But we don't want to just keep trying the same thing over and over again. We want to try in a slightly different way, informed by the failure.
