Volunteerophobia

I like the idea of volunteering, but I'm also afraid of it. My fear is that whatever work I do will consume my time and energy and leave me oblivious to money-making and other productive and social opportunities. I'm also afraid there is zero reward to doing things for free, as indeed has been my experience. I have found that if one does things without being asked, even to the point of volunteering hundreds or thousands of hours, and without expecting compensation, then the recipients, instead of being grateful, may feel rather indifferent or even demand more and more, assuming the attitude of a slave-driver rather than a beneficiary. Over time I have developed what I think is a wise and prudent reluctance to making commitments of the free variety. I can't say I never feel drawn to what may be quixotic projects and ideas from time to time, but that voice of caution has only grown more insistent as I've grown older and more experienced. I think I will have to perceive tangible benefits of some kind before I commit to anything.
