it's because it is hard

ブログも忙しくて、ついつい滞ってしまいます。でもふとOn Writing
を読み返したら以下の文章に目が止まり（ちゃんとマーカーで線引いてた）やはりみんな苦しんでいるんだなあ、と少し元気がでてきました。本当に大変ですよね。

Writing is hard work. A clear sentence is no accident. Very few
sentences come out right the first time, or even the third time.
Remember this in moments of despair. If you find that writing is hard,
it's because it is hard.
