A great Reiki master named Mike Wanner once shared with me that doubt is a serious impediment to progress.
In health and wellness, as well as spiritual and material development, doubt heads us off at the pass before we even try. This is a huge advantage to the doubt. Imagine how powerful you would be if you could act before anything could counteract your action.
Well, you can.
By removing doubt, you eliminate hesitation.
By elimination of hesitation, it is like speeding up time (casting Haste for us real nerdy D&D types!). This is why martial artists can seem like they have ESP about their opponents. Not only have they seen it all before, not only are the neurological connections faster in the visual and motor parts of the brain due to training…
… But they have no doubt about the proper action.
Set your intention. Visualize the outcome.
Reject doubt, because it does not fight fair.
