Whether you're prone to bask in glory or wallow in defeat, venture capitalist Shervin Pishevar suggests practising success and failure amnesia.
Forget that you succeeded. Forgive and forget that you failed. Learn from both and move on fast. Failure can be a patient teacher — it's often a learnable event. Success can lead to signal and pattern blindness. The greatest achievers I have met are grounded and focused. They practice success amnesia. The faster we forget the twins of success and failure and focus on only creating value the faster the engines of achievement can carry you forward.
