Experience usually means that the professional will be more knowledgeable and able. But that is not always the case. And lack of experience is not always a sign of less ability and knowledge. I teach students to become fitness instructors and a few were the type of trainers that I would hire in a heart beat. And I have known some instructor with years of experience who never learned anything new or seemed to care to learn anything new. The taught the same classes and styles for years and were happy to do so. They weren’t bad trainers, but they were missing out on so many new and better ways to affect change in their clients.
If you love what you do, you never work a day in your life, that is an old quote that I don’t recall the name of the oriinator. But if you love what you do, you love to learn all there is to know about what you do.
