Excerpt from the Minimalists: 20/20 Theory
"Anything we get rid of that we truly need, we can replace for less than $20, in less than 20 minutes from our current location. Thus far, this theory has held true 100% of the time. Although we’ve rarely had to replace a just in case item (less than five times this year for the two of us combined), we’ve never had to pay more than $20 or go more than 20 minutes out of our way to replace the item. This theory likely works 99% of the time for 99% of all items and 99% of all people. Including you.
More importantly, we haven’t missed the hundreds of just in case items we got rid of, and we didn’t need to replace most of them at all.
Getting rid of these items clears one’s mind, frees up their space, and takes the weight off their shoulders.
What are you holding on to just in case?"
