If you know RoR is what you want to do then go for it, but prepare yourself before. Here are a few points to consider: - how's the RoR job market in your area? are there openings for entry level? - to some extent you can compensate lack of production experience with personal projects (maybe build something in RoR on github) or by contributing (either with software like bug fixes / features or by getting involved in the RoR community)

good luck!
