I've had similar experiences to what the quote describes. I'm in a bit of a rush and have not actually read the link, but here's my thoughts:

Is the epiphany purely in a way of thinking about things, or does it lead to some material change? In other words, is it actionable? For example, if I come up with new way to frame work for extra motivation, I don't put much stock in it, because I know that my mental state is highly variable and it sometimes just won't work. I write it down, and think about it, and see how long it lasts, but I don't expect it to have a huge impact. I'll put higher stock in things that create some system or make some physical change in the world, like finding out about GTD, nootropics, etc. -- there is a much wider set of mental states in which they will likely work.
