2) Determined: There's no burning desire or anything, but because I've committed myself to finish that wretched novel, no matter how much it drips of cliche, I'm going to finish it. At least to be able to tell myself that I did. There may be varying levels of joy in the process, but the determination is really what pushes me along.
3) Exhausted: There are too many other things to do. I don't know why I'm wasting my time on this thing. I know I should do it, I know that I need to work on my writing, but somehow I can't muster up anything (drive, courage, will-power) to get anything out. I am so discouraged on multiple levels that I often wonder where that insatiable desire went.
Isn't that how it is with anything you love? Whether it be a person (your husband, your sister, your best friend), any other hobbies or even your work. Life fluctuates, as does your resolve and your emotions. Understandable.
The trick is in the "exhausted" stage, one that I often refer to as "burn out", somehow one must find the hidden, often inexplicable energy to continue on. Whether in writing or in marriage, it's all the same. It is in those times, when you really don't want to have anything to do with it, that you really prove your love. As they say, its not real unless its been tested and still stands.
