Penguin sucks; needs help

Ok so I got wc3 ft. I started playing and realized I suck. Now the question is why do I suck, My record for the night was 12 losses 0 wins. And 90% of those games were 3 v 3!. I am not a noob by noob standards, seeing as my ending score is usually average in all departments and i keep up with the number of army and upgrades. So I wanted to know, what the hell am i really doing wrong. The reason I dont think I am a Total noob is because in 3 v 3 games I often am better then one of my partners that are like level 5 and above and my build order is very similar and almost perfect, I creep early like everyone else, i get that second expansion at the right time and alot of times I have a larger army then everyone else. I can honestly chalk up half of the losses due to bad luck (map hacker, spy, people disconnecting, 12 year olds who betray, total, total noobs) all of which I had to deal with in that 12 loss streak, but I shouldent be THAT horrible. The only thing that Might be it is I dont use hot keys at all and that might put be at a slight speed disadvantage but not too much. Anyway, anyone think they can help me out? Maybe if I posted a replay and someone tell me what the hell is making me lose so damn much?
