Meet every new challenge with respect by giving it your full creative attention. Treating new challenges as if they are old ones leads you to apply old methods and solutions, which may or may not fit the current situation. This is especially important to remember if you are an "expert". Expertise is more than experience. It requires the ability to discern what is unique in the present circumstances and to modify old solutions accordingly. Knowledge must be tempered with the wisdom to realize that you don't know everything, and that the present moment is different from any moment in the past. Relying on knowledge alone leaves you frozen in the past. The present is fluid and constantly new, but welcoming if you are willing to plunge in, swim with the tide, and learn new lessons.
