I've come so close to finishing my webbrowser, but I have the "feeling."

The feeling in which I feel like something is missing. So I go to bed everynight and I try to dream some ideas. It works sometimes, hehe.

Other projects though, you think of all this stuff you want, your just about to finish, but than you lose interest. So than you never finish the app.

But like Kedaman and Sam Finch said, it's normal and common.
