James Allen: Living purely today
Do not dwell upon the sins and mistakes of yesterday so exclusively as to have no energy and mind left for living rightly today, and do not think that the sins of yesterday can prevent you from living purely today.
James Allen (28 November 1864 - 24 January 1912) was a British philosophical writer known for his inspirational books and poetry and as a pioneer of the self-help movement. His best known work, As a Man Thinketh, has been mass-produced since its publication in 1902. It has been a source of inspiration to motivational and self-help authors.
