It should be as much as possible a balance between work and pleasure with exercise simply being considered as part of a daily routine. Regular sabbaticals and times of relaxation and mindfulness should punctuate the working day, week and year and these should be considered as mandatory as physical exercise.
Consistent over-workers should be closely observed to ensure they aren’t destroying themselves out of some perceived obligation; However, some people are workaholics and passionate about what they do, as long as it isn’t detrimental to their performance and health making people relax should be seen as a guideline not an enforcible standard. Work can remain a static amount but shifted between personal research, training and duties.
Study time should also be factored in outside of normal working hours. Regularly, say, every 2 years, members should take at least a month long holiday travelling and absorbing other cultures. Or a quiet retreat to friends and family, a long sojourn in a private retreat. The vacation or retreat would be subsidized by the community and the only rule is that the holiday must recorded and a journal be written of things learnt, This will then be placed into the communities library / wiki / openstreetmap e.t.c. Every map and experience will in this way help add to the whole.
