ACIM says that choices are easy when we realize that there really ever are only two choices in any situation, an act of love/communion or an act of fear/separation. So what makes choices seem so complicated sometimes? It's that pesky guilt again. That conflicting, self-defeating, ego-centric habit of ours to doubt that God has our best interests in mind. In lesson 133, it says:

 "And so we come to the criterion for choice which is the hardest to believe, because its obviousness is overlaid with many levels of obscurity. If you feel any guilt about your choice, you have allowed the ego's goals to come between the real alternatives, and thus you do not realize there are but two. And the alternative you think you chose seems fearful and too dangerous to be the nothingness it actually is".

Deep down, I think we are all pretty aware of the choice God would have us make in most situations. We even wear those bracelets that say "WWJD" (What Would Jesus Do). I actually find that question useful when I remember to use it. According to ACIM though, it is a no-brainer. Choose love. Yet, guilt is a hazy cloud that comes over us and makes us believe that there is another way, a more suitable answer. And what does this doubting cause? It causes stress. Stress comes from not trusting. We are told to trust our intuition from all kinds of sources in life and here we are being told again. The thing that separates us humans from the animals is our ability to feel compassion. We are compassionate by nature no matter how much some of us try to resist it. I believe this is what we should use to help us make these tough decisions.

Lesson 133 also says that:  

"Complexity is nothing but a screen of smoke which hides the very simple fact that no decision can be difficult."

Also in chapter 15 of the text:

"Complexity is of the ego and is nothing more than the ego's attempt to obscure the obvious."

Again, decisions are not as complex as we make them out to be. However, some of them may appear to be risky, dangerous, scary, or what have you. This perception should go away more and more as we study and practice ACIM, and continue to trust the source that has only our best interests in mind.
