I’m not a fan of quotes like this because some things are permanent. I lost my leg 6 years ago, that is a permanent situation as it will never grow back. I get the sentiment of the quote but the reality is there are absolutes in life and part of dealing with absolutes is having the wisdom to understand when things are permanent and finding ways to deal with them. The second I lost my leg that was permanent, not coming to grips with situations like this will drive a person mad. Once you come to grips with the things that are permanent it will then allow you to figure out how to deal with that situation so you can move forward versus hoping it will go back to the way things were.
