training overload?

i am training twice a day everyday. i like training and i want to get better but i just feel like sometimes i am being overloaded with alot of different techniques instead of getting really good at one or two. plus i have been getting frustrated more and i never feel fully recovered. at the same time though i dont want to miss a class where we learn something real important. any ideas or suggestions to better my trainging?
