Don’t overthink it. It is what it is. Walls are not straight, and corners are not at ninety degrees. It’s always somewhere in between. What you think exists and what actually does is often an illusion. Accept it and move on. We can only perceive as much or little as we can. So take advantage of this fact and use if for your benefit. Don’t focus on what you cannot control. Let it be. Focus on what you would like to see, and then see it.
