The animal shall not be measured by man. In a world older and more complete than ours, they move finished and complete, gifted with extension of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren; they are not underlings; they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendor and travail of the earth.
— Henry Beston

I am always interested in why young people become writers, and from talking with many I have concluded that most do not want to be writers working eight and ten hours a day and accomplishing little; they want to have been writers, garnering the rewards of having completed a best-seller. They aspire to the rewards of writing but not to the travail.
James A. Michener travail quote

Pain, scorned by yonder gout-ridden wretch, endured by yonder dyspeptic in the midst of his dainties, borne bravely by the girl in travail. Slight thou art, if I can bear thee, short thou art if I cannot bear thee!
— Marcus Annaeus Seneca Seneca The Elder

Art is the stored honey of the human soul, gathered on wings of misery and travail.
— Theodore Dreiser

It is impossible to read for pleasure from something to which you are both father and mother, born in such travail that the writer despises the thing that enslaved him.
— travail quotation by Jim Bishop
