to fight or not to fight

it always good to be busy, i know this. but so far i have been getting ready for fights since before the beginning of this year. 2010 is still very young, i have already fought twice this year. i have an opportunity to fight again in about another six weeks. do i take this fight or do i take some time to get better. i do feel a little like im not improving but just sharpening up what i already have for skills. not sure about this decision since im not hurt and in still very good shape. things to ponder.
