I treat big, non-obvious, hard-to-reverse decisions as a task in my to-do list. When I get to them I take some time to write out the options. For larger projects or projects that involve collaboration, this lives in a working design doc. For smaller or personal projects, I keep this in a per-project journal document. Once the task is checked off, I can mentally free myself from the burden of thinking about the other options. If the decision turns out to cause unforseen problems, I can revisit my notes on why I made the decision and reevaluate with the new information.
