Problems with focusing?

As new Mac user I’m reading a lot of stuff about it. And I’ve realized that apps helping you to focus on some subject are becoming more and more popular. Just to name two there are: Concentrateand Think. They have only one purpose to isolate apps you need to work with at the moment and let you concentrate on your work, so you’re not being distracted by incoming mails, IM messages and so on.
