I will have to say its not a magic pill. Sometimes you need to take action just for the sake of taking action. If you have struggled doing that your entire life, its not going to change over night.
The anti-perfectionist scripting and mentality is also a game changer look at some of the biggest brands and how they started out.
Also the executive functioning really helped me out as someone who has struggled with that their entire life to the point I falsely believed i was incompetent.
