Words

Words will never convey exactly what you mean, whether written or spoken. Communication is so utterly flawed. People will always read into things based on their own experiences and beliefs. They will never fully understand you. 

When I write I feel this desire to be as clear and precise as possible, choosing exact words to convey a very specific meaning or feeling but everyone perceives words differently. Everyone has a different perception, a different emotional experience with any given word. 

They will only understand what their emotional experiences let them. 

Concepts work much the same way, we read into a basic concept bearing with it so much personal emotional background. There's no way any individual will ever fully understand what's going on. 

Is it a waste to try? No, probably not. But it's immensely frustrating as a writer to have that epiphany.
