We are extremely lucky to have what we have, and when life is slinging its arrows into our hearts, it is helpful to remember that. Write down at least 20 things that you are grateful for. If you are going through a tough spell, notice as you are making your list, how your feelings change from negative to more open, accepting and positive.
Read, think and be grateful about the items on your list upon awakening each morning, and start your day right with wonderful feelings of gratitude for what is your blessed life.
For me, remembering daily what I am grateful for and all that I have in my life has been a boon! Starting the day with such positive thoughts sets the tone for my day and makes it easy to be happy.
