My Dear Son:
The static of your own emotions is usually the culprit behind most any situation that is "not right." Masters across the world have spent lifetimes turning down the emotional static so they may engage more fully with inner peace.
Here's something you can try next time you encounter a change of plans: if you will close your eyes and feel a space opening up in front of you, for that is what is really happening, a huge vortex full of possibility and probabilities—then you can step forward with reassurance and not feel like you're running up against a wall.
When plans are changed, it is creation's call for any and every possibility that you can imagine. If you're willing to move forward with equal confidence in the substituted event, that it is actually much more than an event just substituted, then you will be truly blessed.
