The Next Project...?

So at the moment I'm trying to decide whether or not to self publish another book. My first one, the poetry collection, I published in 2006 and it's sat there doing nothing since...but as the publishing service was free it's not like I lost anything by doing it. I thought an angle for the next one could be something like 'a creative writing students guide to year one' and then I could include all my work from last year, so poetry, prose, flash fiction, scripts etc.
I guess if I were the kind of writer who did gigs, like poetry slams etc, a hard copy of my work would be a good idea as it could be sold on from there, but as for just having it on the website, I don't really get anywhere with promotion, and the lack of ISBN means I'm unlikely to get stocked in any shops either. Hmmm. Fingers crossed I'll get to speak to my personal tutor about it, I'm sure she'll have some words of wisdom!
Today I'm trying to be productive, once I've got all my housey stuff done I'm going to crack on with writing :D
