Together much can be done, whether it is work of the mind or work of the spirit.
     Too often we manage to walk through life's storms and we think it must be handled with courage on an individual basis. Group learning is not always successful. It does reach more and there is the social aspect, but too many personalities can not be a good mix. Still, a group learning gives one a chance to listen to differing viewpoints and also the chance for one's own ideas to be, perhaps challenged, but to be evaluated by different personalities. This can give one an expanded look at what might be too narrow a view.
A group does not have to agree, but there must be some compatibility in order to learn from each other. When advancing your knowledge, choose your group carefully.
