Reminds me of the old saying "The only difficult part is to get started". So when I am struggling with starting a huge task, I tell myself that this task consists of parts "a+b+c+d..." but I am only going to do part 'a' today/now. And the surpising part is that when I am finished with part 'a', I am eager to keep on going! You don't have to but you just might.
