I think 10 is a good goal. If you do 10 a day, you'll do 70 a week, or ~300 a month, or 3650 a year. That is certainly a good number to me. If you want to learn more one day, don't stop yourself. But I'd say 10 is a good target. Slow and steady wins the race. I wish I knew that lesson!

用比較科學的方法來學習吧 對非母語人士而言 記憶漢字是一件很辛苦的事 因為不懂漢字的字源 只能憑死硬的功夫磨練 建議先行閱讀 瑞典漢學家 林西莉 的 著作 漢字的故事 http://www.cite.com.tw/product_info.php?products_id=10861 http://en.wikipedia.org/wiki/Cecilia_Lindqvist 應該可以找到該書的 西方語言翻譯本 再則 你想認識多少漢字 建議以用字與用詞頻率來決定目前程度應該要學習的數量 見 http://www.edu.tw/files/site_content/M0001/pin/biau1.htm?open http://www.edu.tw/files/site_content/M0001/pin/biau2.htm?open 貪多務得 細大不捐 不是正確的學習方法 不教 或不學 漢字字源 (小學 / 文字學) 是對外漢語教學的一項重大缺失 只教或只學 "漢字部件" 也只是死硬的記誦而已

Using Heisig's Remembering the Hanzi: 24 Characters every 2 hours.

When I started learning Chinese I would try for 25 every two days. If you limit yourself to only 10 or 12 per day, two hours would be quite enough time to really drill them into your head. Here's my method: 1) Write it out using correct stroke order; 2) Pronounce it aloud in Chinese while (3) thinking of the English meaning. This helped me score an A in class.

I agree with Baystateblue, alot of people do not study more than 25 WORDS a day and remember them. If you are just focusing on just characters and meanings, you could do 50 a day for about a month using mnemonics (memrise I hear is good, as well as hiesigs books). Though I would only recommend doing this a few times.
