You need to think of what is realistically possible to happen. In order to attract someone, you need to be interacting with them, to be around them, to establish connection and communication with them, this is where a square or a working can help you tremendously and build upon what you have established already. But if there is no possible way for you to establish a contact with the people you want to attract (for example you want you attract someone that you saw on the internet), then this will most likely not going to happen only by doing a working alone, because there is no physical way for the energy to manifest itself. This goes for money/wealth workings and anything else in general.
