EDIT: Here are some basic thoughts...
Everything we experience flows through our perceptual sets (composites of relevant emotions, beliefs, behavioral strategies, and intentions), which we can intentionally craft over time. Each component in a perceptual set is processed with varying degrees of attention.
So to program your brain, the first step is to find a functional base line perceptual set to work from & learn how to direct/focus your attention on the different aspects of your perception.
To put it even more simply: go practice all the forms of Buddhism. All I seem to be doing at this point is systematically rediscovering stuff they've known for 2500 years and attempting to put a categorical structure onto it.
