I address my heavenly Father. If I am asking a blessing on a meal, etc., then I pray for that specific thing. In my personal prayers, which some days are almost hourly, and other times I skip a few days (inadvertently), it's rather conversational--but I have a hard time to keep my focus--random songs keep jumping into my head. I've also used a prayer journal, a bit differently: I'd write down all that I was grateful for and those things that I wished to pray over/for, then that helped me to focus my prayers. I also pray while/during/before/after I do devotional study (scripture reading), like it's easier to focus on God when I'm thinking about scriptural teachings. HTH
Answers come to all my prayers. Almost never in words that feel like "God words." Sometimes I'll hear someone say something that resonates perfectly with what I'm struggling with, and I'll know that is the answer. I've read answers, both in books and scripture, sometimes someone calls with something that specifically solves the issue. Sometimes I'll have a feeling. I have always felt that if someone can be the vehicle by which God can answer the prayer, then he will use that person as opposed to a "direct" answer.
