2. Is it your weakness? We all have our loves and obsessions. For me, it is books. I can't walk past a bookstore without going in, and I can't seem to leave one without buying something. But simply being aware of what your weakness is will help strengthen your resolve when you need to. For example, over time I've come to realize that nonfiction books are the ones I most like to keep permanently, so I try to check out current fiction from the library instead.
