“A right commitment is made only after a thorough analysis of our desire. Is it a reasonable desire? Even then, is it really needed? If so, how urgently it is to be attained? What is the price to be paid for? What are the indirect costs? Is it within our limits? Should we involve others on this effort? What are the probable side effects? Many such questions should be asked before a commitment is made. If only the answers to all these questions indicate a positive outcome, our commitment would be logical.”
