The day I bought a ring light, my photography improved immensely. Unfortunately, then I broke the ring light. C'est la vie.
Also, to get a diffuse, but beautiful light, put whatever you're photographing under the light over the stove (if you have one) and cover that light with a coffee filter.
I bought some big artists papers (the huge pieces of colored papers) and boards for this reason, so I wasn't always taking a picture of "something on the stove."
