am I really that much of a geek?

every since Neil put the games out on the bookshelf in the living room i have become somewhat obsessed with the rubix cube of his. And then Neil mentioned seeing something about someone solving one in about 30 seconds I was even more determined. So I went onto YouTube and found a little video about how to do it, but for some reason I am only getting there about 2/3 of the way. Something keeps going wrong in the last few steps, and I can't figure out what it is I am doing wrong. I do realise this makes me sound like a complete geek, but I have always been a bit of a geek anyway so I don't really care... I just want to solve that rubix cube now... at the moment I am once again 2/3 done and only need to solve the last layer

edited a bit later:
I think this one can't be done... I am following the steps exactly and it just messes the whole thing up. This is impossible, I have no idea what I am doing wrong and I am determined to get this done... it has to be done!!!!!

maybe it is time for bed...
