If you are sorting through a pile of stuff, notice if you are making decisions on each item. So often, I work with people who put things aside to “decide later”. That is just putting off the inevitable. There is a saying “clutter is just unmade decisions”. Although it may be hard to do, force yourself to make those decisions now.
In the book “Simplify Your Workday” by Barbara Hemphill and Pamela Quinn Gibbard, they say, “If in Doubt, Decide. Indecision is nearly always the worst mistake you can make. When tempted to postpone a decision, ask yourself: what will I know tomorrow that I don’t know today? If the answer is nothing, just make the best decision you can and move ahead. “
