I don't know about the "law" but I do experience that positive things happen to me when I have a positive attitude and negative things happen when I am negative.
Therefore I, over the last many years, have 'chosen' to be positive about everything. Either I am the luckiest man alive or it works.
Positive people generally have positive friends. Skeptics attract skeptical people. Conspiracy theorists attract nuts. Ha!
Isn't that why girls are always attracted to bad boys? I guess I don't know.
