The link above takes you to a very interesting discussion from heaven4earth.com on how our self-talk or self-concept molds how we set goals, accept success, or achieve. It addresses how we self-sabotage. A very Zen approach.
A related theme is told through short story by 1000 Seeds at http://onethousandseeds.com/2012/05/07/the-giant/#more-703.
I commented on the short story “The Giant” as follows:
You describe a wonderful journey. The sojourner is blind to much of it, though various guides offer to help him. It is so like us, isn’t it, to travel blind to the myriad colors of life around us. Thank you for this tale. It’s lovely.
