In my first marketing class back in college we learned that marketing is about taking wants and turning them into perceived needs. I believe the quote was "Because we know that no one really needs three pairs of red shoes" to which I responded "Of course you do--flats, mid-heels, and high heels." Apparently, marketing had been very successful with me.
Then in one of my accounting classes, we talked about money management. In order to create and stick to a budget, you have to identify what your real needs are. You may really want something, but that doesn't mean you need it. In this case, need trumps want.
A few years after I was out of school, I read an article about managing stress. It stated that there are certain words that contribute to our feelings of stress. These include should, ought and need. Need as in "I need to write two chapters today." Instead, it's less stressful to think, "I want to write two chapters today." Only slightly because two chapters after a full day of work....
Anyway, I've been thinking a bit about want vs. need when it comes to my writing. Because I do feel a need to write. And I don't think that's a bad thing. As a matter of fact, I think it's something that is true for each and every one of the Rogue Pirates (of Snickerdoodle). [Aside: I'm listening to an old radio play on i-Tunes and it's about pirates--arrrr] This is something we have to do. But when I write in my morning pages that I need to write x amount, I do feel a tightening across my shoulders. If I write that I want to accomplish x, the tightness doesn't show up.
So, do you need to write? Do you want to write? Is there a difference? Do you think it would matter if you set goals as things you want to accomplish as opposed to need?
