My way around this is to do "incomplete" simulations. I just need an idea of how it'd feel to be on the task, not finished it. Never simulate to the end, or one of two things will happen: 1. waking up to the harsh reality where it is not done yet, 2. thinking it is done.

E. g. when I need to go grocery shopping, I simulate how I get up, shoes on, grab a bag, think about whether I need a jacket or umbrella, get out of the door, start walking. How would that feel?

I described it in more detail here: https://lemmy.ml/post/36147982
