Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in. If you challenge your own, you won’t be so quick to accept the unchallenged assumptions of others. You’ll be a lot less likely to be caught up in bias or prejudice or be influenced by people who ask you to hand over your brains, your soul or your money because they have everything all figured out for you.
