Reading, and on to read English? And thence to a passion for poetry? My parents taught me to read early because they were fed up with my constant demands for stories, then introduced me to the local library (same experiences as you, when with the grown ip books) and local second hand book shop. There, aged 10, I bought an ancient copy of Palgrave's Golden Treasury, and got completely hooked on poetry. I learned lots by heart, and now have a mind full of quotations from there, as well as elsewhere from my studies and my teaching.
Oh, and etymology too! I did Classics at school - Latin and Greek to "A" Level, and, with French and English, this opened up a whole new world. Anglo Saxon at university just added to my delight in tracing the roots of words.
