Combined the first two sentences for smoother flow, which sounds more natural in spoken and written British English. // “Quite a few” is a common, natural way to say “a lot of” in informal British English. // “Hardest” sounds more natural than “most difficult” in this context for everyday speech. // “Words I don’t know” is simpler and more conversational than “unfamiliar words.” // Added “Honestly” to reflect a more natural expression of feeling. // “Really want to go” is more natural and conversational than just “don’t want to go.”
