I do believe you think what now you speak; But what we do determine oft we break. Purpose is but the slave to memory; Of violent birth, but poor validity: Which now, like fruit unripe, sticks on the tree; 180 But fall unshaken when they mellow be. Most necessary ’tis that we forget To pay ourselves what to ourselves is debt: What to ourselves in passion we propose, The passion ending, doth the purpose lose.
