Interesting post, thanks. Words are spells. To truly program your subconscious, say them aloud, don't just repeat them in your head. You form brain patterns in directing your various muscles to speak the words; then another part of your brain is activated in hearing them. Completing the loop this way makes it much more effective in embedding them in your own subconscious.

I have no real science to back this up, just observations from about 30 years of trying to enhance the capabilities of my own brain with awareness of the subconscious patterns that drive us forward or hold us back. Create a mantra and repeat it to yourself at least 3 times in a row, you need to truly believe in what you are saying emotionally as well as intellectually. Convince yourself it's already true and soon enough it will be.
