William Shakespeare said this quote

“ 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,But fall, unshaken, when they mellow be.Most necessary ’tis that we forgetTo pay ourselves what to ourselves is debt.What to ourselves in passion we propose,The passion ending, doth the purpose lose. ”
