If you want to put yourself in the place of that person, think about you own job, and what you do during your time, and literally imagine a volunteer trying to achieve exactly the same as yourself, but doing it differently, communicating differently, and having a totally different goal at the end of the day to what you would normally do. And doing what you earn a living from, or get paid for, as a gift. How many of you are that sure of your skills, experience and knowledge, not to be unsettled by even a small amount ? And if you were honest enough to say that you would be unsettled, then ask yourself the next question, would you reach the same level of productivity that you would achieve if you were in your usual working environment/conditions ?
