Don't reject new things; accept the lessons they present at face value. It's easy to forget this as we gain more experience and attain a certain position with age. The older and more experienced you get, the more your experience shapes your thoughts. You get caught up in the past and fixed in your ways, unable to shake preconceptions. You start to consider certain things as impossible.
Preconceptions with experience. The need to remain humble and always receptive of new things.
