When we analyze will we shall find ourselves pushed back to the level of attention as the seat of will. The effort which goes into the exercise of the will is really effort of attention; the strain in willing is the effort to keep the consciousness clear, i.e., the strain of keeping the attention focused.
—Rollo May
当我们分析时，我们会发现自己被推回到注意力的高度，作为意志的所在。投入意志的努力是真正的注意力，意志的紧张是保持意识清晰的努力，即保持注意力集中的张力。
