I also thank God for the good things in my life and it ranges from my family to the freedom of my country to the fresh air I breathe. I don't take for granted all of the blessings I have, and I think it is just as important to say a prayer for the good things, and not just when you're asking for something (even when that thing is for someone else).
On a separate and related note, I always want to tell people I am praying for them, but I usually don't say it. I find so many people are not really "into" faith and religion that I don't know what they would think if I said I would be praying for them. But I always do say a prayer. And for those people who don't "believe", I say an extra prayer for them that they will still feel the love of God, even if they don't know what it is, but if they have peace in their hearts, I wish that for them.
If you're not sure how to pray, just speak from your heart, there is no wrong way to do it. Thank God for your blessing, and "let your requests be known unto God" (Philippians 4:6).
Let not your heart be troubled: ye believe in God, believe also in me. John 14:1
