It's not really a license at that point, as I don't think you can impose obligations upon yourself that easily - at least not ones that have legal weight. This seems more like a statement of intent, which is nice I guess. But still, don't write your own licenses. There is no point, and if your software is succesful, at some point someone somewhere will have headaches over whether your license really gives them the legal permission they need.
