As a personal trainer, I know that the greatest predictor of injury is past injury in whatever part of the body we’re talking about. But physical injury and mental efficacy (your belief in yourself that you can do a particular thing) are different. The problem on the mental side is that it’s easy to look back at past attempts and to view them as failures…and this is actually two problems in one. Not only do we let those “failures” define us, but we also bring those things forward as predictors of future outcomes. But, past attempts are simply learning experiences, not failures that define us. So use the past, but don’t let it define you or determine your next outcome. Only you can do that.
