I've been wrong enough times to wonder, is my opinion reality? Sometimes it is not. Sometimes what I think is crazy, and what is rather unexciting to me, is what other people live for. However, there are times when it is a real comfort to know that I'm not the only one who thinks the vegetables might just be rotting.
Sometimes we jump to assume that we are right. I do it all the time, I would put it as a weakness how right I usually think I am. It is important to remember that how we see the world is our opinion of it. It is probably close to reality, but that's an assumption as well. Point being, "is my opinion reality?" is a question worth asking.
