Fyodor Dostoyevsky said this quote
“ Frankly, if there ever was a time when I was really happy, it wasn't during those first intoxicating moments of my success, but long before that, when I hadn't yet read or shown my manuscript to anyone -- during those long nights of ecstatic hopes and dreams and passionate love of my work, when I had grown attached to my vision, to the characters I had created myself, as though they were my own offspring, as though they really existed -- and I loved, rejoiced and grieved over them, at times even shedding quite genuine tears over my guileless hero. ”
