As with many people we meet in our lives we tend to learn the most from the more experienced. Whether it be our college professor, a mechanic, our physician and even our parents.
Experience equates to age as well and how one applies themselves in their field with continued education and the desire to learn.
Along with experience a higher price can be expected (paid) for their expertise and knowledge.
We were once less experienced (“newbees”-“green”) at one point or another and we sought insight to questions we may have had from and experienced person.
Then comes “respect” …we tend to respect the “experienced” from what we have learned from them.
All this can be applied when seeking a personal trainer.
