Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in.
Isaac Asimov, quoted in the Highland County, Ohio, Times-Gazette
We all have assumptions. Whether in our personal lives or work lives, we can’t function without assumptions. The foundation of our decisions is a mix of fact and assumptions. Assumptions are neither a good or bad. They are not bad as they speed up our ability to react, they allow us to work when there are no complete answers, they help us process the complex. They also are not strictly a good thing. They can overly taint reality, they can make facts less understandable, they can cloud our vision when assumptions are communicated as facts.
Understand clearly what your assumptions are and question them every once in a while. Make sure you own them, that they do not own you. You will make better decisions if you do.
