Acting like you have it… isn’t the way, I think. You’d have to feel like you have it 
. Conversely, if you mainly feel desire… unfulfilled desire is a want, a lack, and feeling a lack of something of course attracts more lack 
.
If you ask me, I’d say you have to
- Pick your intent.
- Focus on the outcome (this is where you can visualise how it will look like
, what it will sound like 
, but also how good it will feel )… - … and then energise that feeling and visualisation
.
In my mind, this last point is wrongly skipped over in the “manifestation” books. You have to intend it to become reality. You have to add something. It’s difficult to describe this. I recently tried here, maybe that will help.
