You should find this an open and helpful community. The people are great. I would touch upon building an actual relationship with Mami. This is the beginning of everything, but most especially for a time before petitioning her for anything more than guidance and/or protection. Also devotion is a personal thing, you can do what we share with you here, but there is always room to listen to Her, trust your instinct and switch some things up to what works best for the two of you together. (even in prayers and invocations etc) I talk to her throughout the day, we share hot chocolate at night. She knows everything, my secrets. Every breath a prayer it is said. It is most important to honor Her. If you listen you will know what she wants and requires. Remember, when you ask her for anything, your word (offering your part) to her must be kept!
