i love this question!

as many have already stated, just plunge in and accept that you won’t understand every word and phrase. tolerate ambiguities and uncertainties. it will be such a rewarding and memorable experience, and it will get only better from there.

it takes courage and hard work, but it pays off.

i read A Heart So White by Javier Marias in english when i was in high school and Sputnik Sweetheart by Haruki Murakami in french at university when i was not proficient in those two languages yet, and now i count them among my favorite novels:). never reread in my first languages (am bilingual), no need whatsoever:).
