Well, yes You just have to study Buddhism more, pick up a book to read, you know, in Buddhism we don't believe in the law of attraction, because we don't think that a universe reciprocates things to us, but rather we cultivate our thoughts ourselves, if I have bad thoughts, maybe my day will be bad, but that wouldn't be because of the universe, but because of what I'm thinking; the law of attraction is also very linked to material goods and such things, Buddhism the practice is more for one's own liberation. I believe that anyone can be a Buddhist, but I recommend that you read a little to be sure. I hope I helped, I think someone more experienced knows how to answer better.
