Wow, he sounds like quite the character. I’d not heard of him before, but this here quote did remind me of a similar one about habit-building.

IIRC, the idea there is that after 30-45days or so of doing the same thing on a regular basis, something then becomes a ‘habit,’ and out of building such life-habits, one can even alter one’s character so to speak. Or at least have a significant impact on one’s growth and effectiveness in life…

Also, “James Allen” has got to be one of the most common names in English, so the ID would certainly need to be researched(!)
