James Allen, born in 1864, was one of the first British authors to write books on personal development and self-help.
His most famous work "How man thinks, so he lives" (1903) is one of the most widely read works on this subject and is still a great source of inspiration for many self-help and motivational therapists to this day. He came from a working-class family, but made it to the position of private secretary and eventually manager of a company. He later retired and devoted himself to writing. He died in 1912 at the age of 47.
