Time to... Time to... Time to choose my first notebook

Yes, I am slowly going to get my first computer in my life. But I have to choose it and that's the problem - I do NOT know how to choose a good one. Yes, I understand words like RAM memory, HDD, processor and the only thing I look at is the number. "Only 1GB of RAM? Not for me - I wanna more and more..." That's my style. I know, that I have to look at the RAM speed but I don't know, what's good...
