Affirmations are sometimes best done one at a time. The more you focus on one goal at a time, the faster is will manifest into your life. Also keep it simple until you feel comfortable with complex affirmations. I like simple ones that I can repeat all day, or when ever I feel down.
If my mood changes and I want to pull myself out of a funk I remind myself..."I am peace, I am joy, I am light, I am love, I am kind, I am honorable, I am honest, I am amazing, I am unique, I am strong, I am Herbalist, I am wife, I am teacher, I am mother...." As I repeat these words, I remind myself of who and where I am in life, as well as add what I aspire to me. Often times I'll add the opposite of what caused me to be momentarily sad.
You are well on your way to having better control of your thoughts, mood, life, and all that you attract into it.
