Why only some of my affirmations work? Do you think it’s all bs?

Hi all! Why do only some types of positive affirmations work for me? The type that works are about conparison or/and personal qualities e.g. “I’m becoming so extroverted as (name of a friend)”. However those for jobs like “I work at a job that gives me pleasure” produce the opposite results - I got fired on the day I repeated that! Oh and yesterday I was told I no longer qualify for a job... right after repeating “I am a magnet for money”. What gives?

My second question is would you say brainwaves like isochronic tones, Royal Riffe frequencies or binaural beats work better than doing affirmations or listening to someone repeating them?
