>>12875446Build systems, start with small things. I have one with a whole deck of cards in a 2d list for each suit. I laid it out on the table at first. Flip through a deck and mark off cards as you see them. You can tell which cards are still in the deck because the eyes are exceptionally good at small 2d grids.
One more thing to always pay attention to for visual awareness: everything has dimension NOTICE IT, I can't emphasize how important this is. I don't mean list all of the details you see in sublingual vocalization. Feel(see) the dimensions. One of my favorites right now is noticing very fast things and freezing that feeling in my mind, just trying to make faster reaction times.
