I bought myself a whiteboard. And on it I write down all the tasks (large and small) and milestones to completing my project. The board obviously goes through revisions as the project grows and morphs. But it does something really important that I wasn't doing before. I too get a thrill from starting a new project because it's still just a dream but seems acheivable. There's probably some cogsci reason for this, dopamine levels and so on. And when the project starts to drag on you're not getting that dopamine hit anymore and so you get an urge to start a new project to get that rush again. What you need to do is learn to get a thrill from completing milestones. Being able to cross off one of the tasks on that whiteboard feels awfully damned good. I keep the crossed off tasks on the board for a while because I find that thrill of completing it lasts for a while and keeps me motivated to cross off the next one.
