Your choice if you want to hold onto the the further development of that self limiting belief.

There are additional 3D stereograms to try at that site. You can print them out and play with them for a while. I printed out a set of 12 and looked at them 3 times a day for a couple of days afterwards I found that I had the blip page easily and it stayed there too.
If you're refering to the stereogram in the PhotoReading manual. Yes that's a tricky one it gives a cave like effect since the letters are near the edge.
