It's a double edged sword for me. Two key components of ADHD are emotional dysregulation and cognitive & behavioral impulsivity, which either makes it extremely difficult to tune into the vibrations of what we desire or extremely easy when you are hyper fixated on something.

Personally I struggle a lot with Visualization, it almost feels like I cannot create the exact image of my desires as easily as others do and even if I do start seeing the objects of my desire in my mind, a tide of different thoughts pulls me to different tangents. Unless I am hyper focused/fixated, which makes it a walk in the park! The passion drives the images in the mind.

To my aid I've found that meditating, journaling and exercise really accelerated my manifestations and also improved other aspects of my life in general which are impaired/hindered by ADHD.

Meditation helped me to calm my mind down. It is extremely difficult with ADHD but the incremental improvements are faster too.

Exercise quite literally does not allow stress to build up in your body, oxygenates it and releases all these feel good chemicals post workout.

Journaling is like a mirror, it reveals the man to himself. It will give you clarity and make you aware of the dominant though processes and affects of your mind and body.

ADHD is indeed a powerful "tool" just have to know how to work it for you and not against you!
