把这一句，留给此刻的你

I can fairly be called an amateur because I do what I do, in the original sense of the word - for love, because I love it. On the other hand, I think that those of us who make our living writing history can also be called true professionals.

我可以被公平地称为业余爱好者，因为我做我所做的，在最初的意义上的词-爱，因为我爱它。另一方面，我认为我们这些以写历史为生的人也可以被称为真正的专业人士。
