The best way to overcome past memories is only by living new experiences and creating new memories.
Before we race others its important that we race ourselves and that means overtaking where our last memories ended and going ahead. Nothing is a failure for life, it is just the first or nth iteration of failure beyond which there is success. The willingness to fall and get up and take a go at it again distinguishes achievers from non-achievers. We are wired to think in this current day and age that there isn’t enough time but we can focus on the things that matter to us and leave everything else behind. Do it over and over again, learning with each iteration for the next attempt. Falling and failing are temporary. Achieving meaning is for life.
