“You know the people that say to you they have 15 years experience when they mean one year 15 times?”
In some fields these folks are masters. Like a blacksmith or a carpenter, where one gets better with time.

However, in some fields this repeat mindset is pure dangerous as the field morphs and swirls on a yearly, monthly, and even daily basis.
Imagine your IT guy still used an apple computer from 1984. Would you hire him?
Why then would you go to a Doctor who graduated in the 70s, 80s, or even 90s and the only continuing education they got was from pharmaceutical companies?
Why would you go to a strength coach that doesn’t do an initial assessment?
This is a free market. Ask for CVs. Ask for resumes. Ask for testimonials. Ask what professionals have done lately to be a leader in their field. Be a smart consumer. It is a powerful job because you decide who stays and who goes.
