I'm getting a grad degree in English, and am looking for some general tips to help me survive and succeed grad school.  

I think that doing things like 

-taking extra classes, even undergrad, will get me up to speed

-free writing daily, I prefer poetry as a genre, but like criticism as well

--reading at least 150 pages a day, my head needs to always be in a book or a journal of my writing

Is there anything else that would be recommended? I'm sure that I'm missing a lot.

I think I have Adult A.D.D. Does that count?

Adult Add? Well cool, is it at least the funnier hyperactive version?

Also, I got my undergrad in business and did well in the fresh composition classes, but this is a whole new level of fun that I'm taking on.

Well, i have an undergrad english degree... What you are doing sounds good. Only thing i would recommend is maybe broaden your free writing genres. Do some short stories, maybe some screen plays, that sort of thing. Most important would be the criticism though...

No it is the inattentive to details career affecting version.
