请教：推荐信中要求写的个人的缺点能写哪些方面呢？

Honestly, don't worry too much about this. Everyone has weaknesses. Typically what's more important is that you are aware and working on improving on your weaknesses, rather than trying to say that you only have weaknesses that aren't really (eg. too much of a perfectionist, too results-driven, etc). If your recommender asks for your input, you might explore telling him what you think are your own weaknesses and what you're doing to improve them, and then suggest that he make his own judgment on what to write. (Sometimes it may also be unrealistic for someone to be working on all his weaknesses at once too, so be wary of that.)
