Do you believe in Luck?

Recently i have gotten a Mayan necklace which is supposed to be good luck, and so far it has been. Girls have started noticing me more, i feel like i fit in more because i now have a close group of about 10 friends (we were all friends before were just closer now) and just generally lucky things have been happening. Do you believe this was from the necklace? I know, i sound crazy
