Be Here Now (1971)
Context: I'd get to a point with my colleagues when I couldn't explain any further, because it came down to "To him who has had the experience no explanation is necessary, to him who has not, none is possible.".
“He who jumps into the void owes no explanation to those who stand and watch.”
“And no one believes the explanation anyway.”

Context: I never dwell on past mistakes… There is too much to plan for the future to waste time complaining. Elsie Mendl was a great friend of mine for many, many years.

You’re reminded again of the mistake. And no one believes the explanation anyway.
