Here is a personal program geared toward increasing happiness and joy:
"I am now committing my mind and resources to continue developing all of my character traits, especially the traits of being happy and joyful. Every moment I choose my thoughts, feelings, words, and actions, so right now I will choose to be happier and more joyful.
This moment is the only moment I can live in, and therefore at this moment I choose happiness and joy. I am grateful for all the good in my life, for each and every breath, and for life itself. Every moment of happiness and joy that I have ever experienced is stored in my brain and my brain is always with me. I will access that joy to easily speak and act joyfully and kindly. My own joy enables me to be kinder and more compassionate towards others. I will think of positive role models who have a balanced sense of happiness and joy, and I will keep learning from those role models.
I will keep developing the mind-set of someone who is constantly happy and joyful. I will become happier and more joyful all the time. It is becoming easier to be happy and joyful. I access and create more happy and joyful moments.
I ask My Father, My King, Creator and Sustainer of the universe, for the wisdom and insight to develop all of my character traits, especially the quality of being happy and joyful in a balanced way. My happiness and joy enables me to think, speak, and act at my best. I am grateful for each happy moment. My own happiness will be able to help others. I will find it easier to grow in happiness and joy."
