The ability to give time, energy and professional skills free of charge is a privilege. It is a privilege that not everyone has to begin with, but that we can also lose as our responsibilities increase or as we start to lose the youthful ability to pull all-nighters. Perhaps we begin to realize how much that free work is taking us away from our families, friends, and hobbies; away from work that might improve our situation and enable us to save for the future.
