How to make Ubuntu to start faster

My Ubuntu used to start really slowly, even more slowly than my former XP. It was not really a problem except on the mornings when I wanted to surf while eating my breakfast. I was finished with it when my laptop was finally ready to be used. So I thought that there has to be a way to make it faster. After a little research I learned that it was not even hard to do. I gave it a try and now this machine starts a lot faster. Whoa! Totally worth it.

I tried to find a decent tutorial in English but I couldn't find any. So I'm writing my own instead. But I'm not expecting any of my regular readers to be interested. I just believe in the power of Google. One day some Ubuntu noob searches for "how to make Ubuntu to start faster" and ends up here. And voilà, here is the how-to.
