Orison Swett Marden Quote

Just because you are struggling on a farm or in a factory, doing something against which your whole nature rebels, because there is no one to help you support your aged parents or an invalid brother or sister, do not conclude that your vision must perish. Keep pushing on as best you can, and affirming your divine power to attain your desire. Hundreds and thousands of poor boys and girls with poorer opportunities than yours have done immortal deeds because they had faith in their ideal and in their power to attain it.
