Yes I do absolutely - but it's not quite as simplistic as that - there is a lot more to law of attraction than just "wishing" and "waiting" for stuff to happen. In fact there are several laws that work together - I've done a few hubs on this subject you can check out if you are interested.
I know that what we put forth does come back. If you want abundance, be generous. If you want acceptance, be tolerant etc.
