CRAP my PI just finished giving me a lecture about how i am doing too much and have spread myself out too thin and need to prioritize....ive been getting everything accomplished in lab just taking longer than expected because im learning EVERYTHING (procedures, etc) on my own..and im the only undergrad in the lab filled with medical residents and MD/PhDs...he wants me to take less credit hours next semester(taking 24 credit hours which is true i do need to take less)..he tried to spin it in a positive way by saying i know your very bright but blah blah..and he gave me a freaking A- for my research saying that he was only giving me that grade to motivate me and show that there is room for improvement....should i forget about asking him for a LOR?????...i know he doesnt HATE me or anything but still...CRAP
