Thank you for this interesting article. I sincerely hope that you are wrong though, for my own sake. I don´t have a muse, and I don´t know if I will ever have one, But I have been inspired by different life experiences, both good and bad, and I believe there is a trick to using happiness for inspiration:
Channel it, and do not be obsessive about it, especially if the source of the happiness is romantic and/or sexual.
That's an interesting perspective! I definitely don't want to limit sources of inspiration; I've just noticed a lot of patterns. But maybe a different approach is key sometimes.
