The late James Doty, a neurosurgeon and professor at Stanford University, wrote in his 2024 book "Mind Magic" about how meditation paired with repetition of messages can change a person's subconscious. This could look like closing your eyes before bed to relax, meditating and visualizing an intention like earning a new job title or mastering piano. Afterward, write the intention on a piece of paper and keep it nearby, reading it often.
