"self-promoted denial"??? BAH. What kind of YUCK-speak is that????
How about, "Self-promoted respect". You don't know how you will feel at the end of the time period, what you will want, what you will tolerate. No need to issue an ultimatum to yourself. That doesn't mean you are in denial or avoiding anything. It means that you are committing to something manageable right now and are realistic enough and caring enough of yourself to revise your aims in light of new information you gather during the time period. Come on, you should be proud of your capacity to take responsibility for whatever is next while recognizing it is uncertain and only time will bring news of the future. That is a strong, empowered position.
"self-imposed denial" JEEZ!!!!
You talk nice to yourself Grasshopper and respect that in yourself that you would respect in others.
